Build IoT with Raspberry Pi: A Practical Guide to Projects & Setup

Building an Internet of Things (IoT) project used to feel like a major undertaking, but the Raspberry Pi completely changed the game. This tiny, credit-card-sized computer is the perfect brain for your connected devices, making the combination of IoT with Raspberry Pi an ideal starting point for just about anyone, from hobbyists tinkering in their garage to professionals developing a new product.

What I love about it is the sheer flexibility it offers. You get a powerful platform to connect sensors, crunch data, and send it over a network, all without a steep learning curve or a massive budget.

Why Is the Raspberry Pi So Good for IoT?

At its heart, any IoT system boils down to three things: sensors gathering data, a device to process that data, and a network to share it. The Raspberry Pi fits perfectly in that middle role, acting as the bridge between the physical world of sensors and the digital world of data. It hits a sweet spot that simpler microcontrollers (like an Arduino) can't match and that industrial computers often overshoot in cost and complexity.

Where an Arduino is excellent for simple, repetitive tasks like blinking an LED or reading a single sensor, it lacks a full operating system. A Raspberry Pi runs Linux, giving you networking, multitasking, and the power to run complex applications and services right on the device. This makes it a far superior choice for IoT hubs or devices that need to perform on-device data processing, often called "edge computing."

The real magic lies in the Raspberry Pi's General Purpose Input/Output (GPIO) pins. These pins are your direct line to the world of electronics, letting you hook up an incredible variety of components.

• Sensors: Easily connect sensors to measure temperature, humidity, motion, light, pressure—you name it.

• Actuators: You can also control things. Drive motors, flip relays, light up LEDs, or move servos to make your project physically react to data.

• Connectivity: With Wi-Fi and Bluetooth baked right in, getting your project online and talking to other devices is a breeze.

Essential Components for Your First Raspberry Pi IoT Project

Getting started is pretty straightforward, but you'll need a few key pieces of hardware and software. Think of this as your starter kit. Each component has a specific job, and choosing the right one can make your project a lot smoother.

Once you have these parts, you're well on your way. The combination of a Raspberry Pi, a good SD card, and a reliable power supply forms the core of almost any project I've built.

Choosing the Right Pi for the Job

Not all Raspberry Pi models are built the same, so picking the right one comes down to what your project actually needs.

• For High-Performance Needs: If you're building something demanding, like a home security system that has to process live video streams from a camera, you'll want the extra muscle of a Raspberry Pi 4 or 5. Their powerful CPUs and ample RAM can handle complex tasks like real-time object detection.

• For Low-Power Applications: If you're creating a simple, battery-powered weather sensor that just needs to wake up and send a temperature reading every few minutes, a Raspberry Pi Zero 2 W is a fantastic, power-sipping choice. It's ideal for devices that need to be small and efficient.

A Growing Force in the IoT Market

The Raspberry Pi isn't just a niche tool for enthusiasts; it's a major player in the IoT industry. Development kits based on the Pi are a key part of a global IoT market valued at roughly $1.2 billion, a figure expected to balloon to $3.5 billion by 2033. This surge is fueled by the rise of automation and AI-powered IoT in sectors like manufacturing and environmental monitoring, where the Pi delivers real-time edge processing without the hefty price tag.

Business Value: The business adoption of Raspberry Pi in IoT is driven by its low cost of entry and rapid prototyping capabilities. Companies can develop and test proof-of-concept devices for a fraction of the cost of custom hardware, significantly reducing R&D risk and time-to-market.

This ability to handle data locally—on the "edge"—is a really important concept in modern IoT. Instead of flooding your network by sending every single sensor reading to the cloud, the Pi can analyze the data on the spot, make a decision, and only transmit what's truly necessary. This cuts down on delays, saves bandwidth, and is a cornerstone of smart, scalable IoT design.

If you're curious about how this local processing fits into the bigger picture, learning more about the role of cloud computing in IoT will show you how edge devices and cloud platforms work together. This balanced approach is what makes your system efficient, whether you're building one smart gadget or a whole network of them.

Getting Your Pi Ready for Headless IoT Work

Most of the time, your IoT with Raspberry Pi projects won't be sitting on a desk with a monitor, keyboard, and mouse. They'll be tucked away in a closet, perched on a shelf, or deployed out in a field somewhere. This "headless" approach is the most efficient and reliable way to run an IoT device, but it means you have to get it ready for remote access before you even power it on for the first time.

The trick is to do all the important setup work directly on the microSD card.

Trust me, this pre-boot configuration is a massive time-saver. Instead of juggling peripherals just to type in a Wi-Fi password, you can have your Pi connect to the network and be ready for your commands the moment it gets power.

Prepping the SD Card for Remote Access

First things first, you need to flash the operating system onto your microSD card. The official Raspberry Pi Imager tool is your best friend here. It handles downloading the latest Raspberry Pi OS and writing it to your card flawlessly.

The real magic for a headless setup happens in the advanced options menu, which the Imager presents during the flashing process. This is where you pre-configure everything:

• Enable SSH: This is non-negotiable. Secure Shell (SSH) is the protocol that lets you log into your Pi's command line from another computer on your network.

• Set a Hostname: Give your Pi a memorable name like weather-station.local. It makes it much easier to find on your network later.

• Configure Wi-Fi: Punch in your Wi-Fi network's name (SSID) and password here. When the Pi boots, it will connect automatically.

• Set Username and Password: Please, create a secure login. Using the default credentials is a huge security risk you don't want to take.

Once the Imager has worked its magic, you've got an SD card that’s good to go. Just pop it into your Raspberry Pi and plug in the power.

Pro Tip: Give the Pi a couple of minutes to boot up on its first run. It needs a moment to connect to the Wi-Fi. After that, you can connect from your main computer's terminal with a command like ssh your_username@hostname.local.

Your First Commands After Logging In

Once you're logged in via SSH, the first order of business is to update the system. Running on outdated software is just asking for trouble, especially for a device connected to the internet.

These two commands are your bread and butter. The first one refreshes the list of available software packages, and the second one upgrades everything to the latest version.

sudo apt update
sudo apt full-upgrade -y

Running these ensures your Pi has all the latest security patches and bug fixes. It's a simple habit that makes a world of difference for the long-term reliability of your project. A secure IoT device is a happy IoT device.

Switching On the Hardware Interfaces

To talk to sensors, your Raspberry Pi uses specific hardware communication protocols. For most IoT projects, the ones you'll care about are I2C and SPI. These are disabled by default to save resources, so we need to switch them on.

The easiest way to do this is with the Raspberry Pi Configuration tool, right from the terminal.

1. Run the command sudo raspi-config.

2. Use the arrow keys to navigate down to Interface Options.

3. Go through and enable I2C, SPI, and Serial Port one by one. The tool will ask if you want the kernel module to be loaded automatically at boot—say yes to this.

4. When you're done, exit the tool and reboot the Pi when it prompts you.

With these interfaces enabled, you've unlocked your Pi's ability to communicate with a massive world of sensors, displays, and other peripherals. This is the final step that turns your device from a simple networked computer into a true IoT hub, ready to collect data and publish it with a protocol like MQTT. To see where this is headed, check out this great beginner's guide to getting started with MQTT, which is the perfect next step for your newly configured Pi.

Connecting Sensors and Reading Real-World Data

Alright, your Raspberry Pi is now set up and on the network. This is where the real fun begins. It's time to connect the software to the physical world and turn that silent little box into a device that can actually sense its surroundings. The magic happens through the Pi's General Purpose Input/Output (GPIO) pins—think of them as the nervous system for your project.

Before we start plugging things in, it's worth remembering that a solid, headless setup is the foundation for any reliable IoT device. Getting this right means you can build and deploy your project anywhere, without ever needing a screen or keyboard attached.

With that foundation in place, let's get our hands dirty.

Wiring Your First Sensor: A Smart Weather Monitor Example

Let's build something genuinely useful right away: a simple smart weather monitor. For this, I recommend the DHT22 sensor (sometimes sold as the AM2302). It's a go-to choice for hobbyists and pros alike because it reliably measures both temperature and humidity. Best of all, it’s a digital sensor, which means it handles all the messy analog-to-digital conversion on its own and gives the Pi clean, ready-to-use data.

Hooking it up is pretty simple. The DHT22 usually has three or four pins:

• VCC (Power): This goes to a 3.3V or 5V pin on your Pi.

• GND (Ground): Connect this to any Ground pin on the Pi.

• Data Out: This is where the sensor sends its readings. We'll connect it to GPIO4.

• NC (Not Connected): If there's a fourth pin, you can just ignore it.

You'll also need a 10kΩ pull-up resistor between the VCC and Data pins. This little component is crucial because it keeps the data line in a stable "high" state when it isn't sending data, preventing weird, inaccurate readings. The good news is that many DHT22 sensors sold on breakout boards already have this resistor built-in, which makes life even easier.

A Word of Caution: I can't stress this enough—always double-check your wiring before powering on the Pi. If you accidentally connect a power pin to a GPIO pin or get your connections crossed, you can permanently fry your Raspberry Pi. Take a moment to be sure.

Reading Sensor Data with Python

Now that the hardware is sorted, we need some code to talk to it. Python is the perfect language for this on the Raspberry Pi, mainly because of its simplicity and the massive ecosystem of libraries available. We'll use the Adafruit CircuitPython DHT library, which makes reading the sensor an absolute breeze.

First, pop open your SSH session and install the library:

With that installed, create a new Python file—let's call it weather_reader.py—and paste in the following code.

import time
import board
import adafruit_dht

# Initialize the DHT sensor on GPIO4.
# The `board` library handles the pin mapping for you, which is super convenient.
dhtDevice = adafruit_dht.DHT22(board.D4, use_pulseio=False)

# This loop will run forever, grabbing a new reading every 2 seconds.
while True:
    try:
        # The library does all the heavy lifting of timing and reading the data.
        temperature_c = dhtDevice.temperature
        humidity = dhtDevice.humidity

        # Let's print the readings to the console.
        # f-strings make formatting the output nice and clean.
        print(
            "Temp: {:.1f} C    Humidity: {}% ".format(
                temperature_c, humidity
            )
        )

    except RuntimeError as error:
        # Errors are normal with sensors. This catches common read failures.
        print(error.args[0])
        time.sleep(2.0)
        continue
    except Exception as error:
        # If something else goes wrong, we'll exit gracefully.
        dhtDevice.exit()
        raise error

    # Wait two seconds before the next reading.
    time.sleep(2.0)

Save the file and run it with python3 weather_reader.py. You should see live temperature and humidity data streaming into your terminal. Just like that, you've built a functional data-gathering node!

Digital vs. Analog Sensors: Knowing What to Use

The DHT22 we just used is a digital sensor, but you'll run into plenty of analog ones, too. Knowing the difference is critical for choosing the right part for your project.

Here’s the key takeaway: the Raspberry Pi does not have a built-in Analog-to-Digital Converter (ADC). This is a huge distinction from boards like Arduino. If you want to use an analog sensor—say, a simple light-dependent resistor or a basic soil moisture probe—you'll need an external ADC chip (the MCP3008 is a popular choice) to act as a translator between the sensor and the Pi.

So when do you pick one over the other?

• Go Digital: For most common measurements like temperature, humidity, and pressure (e.g., BME280, SHT31). They are generally easier to wire, more accurate, and less susceptible to noise.

• Go Analog: When you need to measure a continuous value where a digital option is unavailable or too pricey. Think light intensity from a photoresistor or moisture from a simple two-prong soil probe.

Getting MQTT Set Up for Device-to-Device Chat

Okay, so your Raspberry Pi is now successfully grabbing data from a sensor. That’s awesome. You've essentially built a tiny, data-collecting outpost. But for this to be a real IoT with Raspberry Pi project, that data needs to go somewhere. This is where we bring in the Message Queuing Telemetry Transport, or MQTT.

MQTT is a messaging protocol built from the ground up for the kind of constraints you see with IoT devices. Forget the clunky, heavyweight model of HTTP. MQTT uses a much smarter and more efficient publish-subscribe (pub/sub) model. This approach is a lifesaver for low-power gadgets that might be on a spotty Wi-Fi connection, as it keeps bandwidth use to a minimum and makes sure messages find their way without constant checking.

The Core Idea Behind MQTT

Getting your head around the pub/sub model is the most important part. I like to think of it like a magazine subscription. Some devices are journalists (the publishers) writing articles (the data) about specific topics. Other devices are readers (the subscribers) who only get the topics they’ve signed up for. The magazine's main office, which handles all the distribution, is the broker.

Let's break down the key players:

• Broker: This is the central server. It’s the traffic cop of your IoT network, receiving every message from publishers and making sure it gets delivered to the right subscribers.

• Client: Any device that talks to the broker is a client. A client can publish data, subscribe to data, or even do both. Your Raspberry Pi will be acting as a client.

• Topic: This is just a simple text string that works like an address for messages. For our little weather station project, a topic like home/livingroom/temperature is perfect.

• Publish: The act of sending a message to a specific topic on the broker.

• Subscribe: The act of telling the broker you want to receive any messages sent to a particular topic.

What makes this so powerful is that everything is decoupled. The sensor publishing the temperature doesn't need to know or care about the device that's going to display it. It just fires the data off to the broker, and its job is done.

Installing a Mosquitto MQTT Broker on the Pi

For a lot of my own home projects, I just run the MQTT broker directly on one of my Raspberry Pis. It creates a neat, self-contained network that's perfect for smart home tinkering. The go-to open-source broker is Mosquitto, and getting it installed is dead simple.

First, SSH into your Pi and run these two commands:

sudo apt update
sudo apt install mosquitto mosquitto-clients -y

This one-liner installs both the Mosquitto broker software and a handful of command-line tools that are super useful for testing.

To make sure the broker starts up automatically every time your Pi reboots, you just need to enable the service:

sudo

And that's it. Seriously. You now have a fully functional MQTT broker running on your local network.

Publishing Sensor Data with a Python Script

Now for the fun part. Let's tweak our Python script to actually publish the sensor readings over MQTT instead of just printing them to the screen. We'll use a very popular Python library called Paho-MQTT.

First, get the library installed:

Next, open up your weather_reader.py script and modify it to look like this. This code is set up to connect to the local broker we just installed on the Pi.

import time
import board
import adafruit_dht
import paho.mqtt.client as mqtt

# --- MQTT Configuration ---
MQTT_BROKER = "localhost"  # Use the Pi's IP if connecting from another device
MQTT_PORT = 1883
MQTT_TOPIC_TEMP = "home/livingroom/temperature"
MQTT_TOPIC_HUMIDITY = "home/livingroom/humidity"

# --- Sensor Initialization ---
dhtDevice = adafruit_dht.DHT22(board.D4, use_pulseio=False)

# --- MQTT Client Setup ---
def on_connect(client, userdata, flags, rc):
    if rc == 0:
        print("Connected to MQTT Broker!")
    else:
        print("Failed to connect, return code %d\n", rc)

client = mqtt.Client(client_id="rpi_weather_station")
client.on_connect = on_connect
client.connect(MQTT_BROKER, MQTT_PORT, 60)
client.loop_start()  # Starts a background thread to handle the network connection

while True:
    try:
        temperature_c = dhtDevice.temperature
        humidity = dhtDevice.humidity

        if temperature_c is not None and humidity is not None:
            # Publish the temperature reading
            temp_payload = f"{temperature_c:.1f}"
            client.publish(MQTT_TOPIC_TEMP, temp_payload)
            print(f"Published to {MQTT_TOPIC_TEMP}: {temp_payload}")

            # Publish the humidity reading
            humidity_payload = f"{humidity:.1f}"
            client.publish(MQTT_TOPIC_HUMIDITY, humidity_payload)
            print(f"Published to {MQTT_TOPIC_HUMIDITY}: {humidity_payload}")

    except RuntimeError as error:
        # Errors happen, just print them and carry on
        print(error.args[0])

    time.sleep(10.0) # Send new data every 10 seconds

Run the updated script with python3 weather_reader.py. Your Pi is now officially publishing real-time sensor data! Any other device on your network can now subscribe to the home/livingroom/temperature and home/livingroom/humidity topics to get these updates instantly.

Knowing when to use MQTT is a key design choice. If you want to dig deeper, you can learn more about when and where to adopt MQTT in your tech stack to make the best decisions for future projects.

The Raspberry Pi has become a massive player in the IoT world, especially as a low-cost, flexible gateway device. The global market for Raspberry Pi gateways was pegged at around $1.1 billion in 2023 and is projected to hit $3.2 billion by 2032, growing at a CAGR of 12.3%. This explosive growth shows just how central it is for connecting IoT devices, a trend you can explore in the full Raspberry Pi gateways market report.

Inspiring IoT Project Ideas and Use Cases

Alright, you’ve got the basics of setting up your Pi, wiring sensors, and getting MQTT to talk. Now for the fun part: turning all that technical know-how into something tangible and genuinely useful. A Raspberry Pi IoT setup is more than just a cool tech demo; it’s a toolkit for solving real-world problems.

Let's walk through a few project blueprints that show just how versatile this little computer can be, from making your home smarter to adding mission-critical intelligence to industrial machines. I’ve picked these examples to be practical roadmaps you can build upon for your own projects.

Use Case 1: Smart Home Environmental Control Hub

Imagine a system that does more than just report the temperature—it actively manages your living space to keep it comfortable and healthy. This project evolves our simple weather monitor by adding actuators to take control of the environment.

• The Goal: Automatically manage a room's temperature and air quality.

• Hardware You'll Need:

  • Raspberry Pi 4 Model B

  • A BME680 sensor (this thing is great; it measures temperature, humidity, pressure, and air quality/VOCs)

  • PIR motion sensor (to know if someone is actually in the room)

  • A 5V Relay Module (this lets you switch an existing fan or heater on and off)

• The Logic: The Pi constantly polls the BME680 for data. If the motion sensor sees someone enter the room and the temperature climbs above 24°C, it triggers the relay to switch on a fan. If the air quality (VOC level) gets poor, it could activate a different relay connected to an air purifier.

The real-world value here is all about energy efficiency. By only heating or cooling occupied rooms, you stop wasting electricity. You can apply the exact same logic to lighting to build a truly responsive smart room.

Use Case 2: Automated Garden Watering System

Keeping plants happy can be a real balancing act, especially when the weather is unpredictable. This project uses soil moisture data to give your plants exactly the right amount of water, saving them from both dehydration and root rot.

• The Goal: Water plants automatically based on how thirsty the soil actually is.

• Hardware You'll Need:

  • Raspberry Pi Zero 2 W (its low power consumption is perfect for this)

  • A Capacitive Soil Moisture Sensor (I strongly recommend these over the resistive types; they last much longer)

  • A small 5V Water Pump and some tubing

  • A 5V Relay Module (to safely control the pump)

• The Logic: Your Pi wakes up every few hours to check the soil moisture sensor. If the reading drops below a threshold you've set (say, 40% moisture), it flips the relay on, running the water pump for a specific time, like 15 seconds. All this data gets published via MQTT, so you can check on your garden from anywhere.

A key takeaway from this project is the power of a closed-loop control system. It's not just running on a dumb timer; it measures a condition, acts on it, and can even measure again to see if its action worked. This is a core principle in any effective automation.

Use Case 3: Industrial Machine Monitoring

Don't let the Pi's size fool you; it's not just for hobbyists. The industrial world is adopting Raspberry Pi for serious IoT work. In fact, the global industrial Raspberry Pi market hit around $1.2 billion in 2023 and is projected to climb to about $3.5 billion by 2032. This is because they're fantastic for retrofitting older, "dumb" machinery with smart monitoring. You can learn more about this trend by checking out these insights on the industrial Raspberry Pi market.

• The Goal: Monitor a machine for early warning signs of failure using vibration and temperature data.

• Hardware You'll Need:

  • Raspberry Pi 4 Model B

  • An ADXL345 Accelerometer (for measuring vibration)

  • A DS18B20 waterproof temperature probe

• The Logic: This is where things get more advanced. The goal is predictive maintenance. Instead of just reacting when a machine breaks, you can spot anomalies in its operation—like a sudden increase in vibration or a creeping temperature—and schedule maintenance proactively. This simple act can save companies a fortune by minimizing downtime.

To make this work, your code needs to do more than just read sensors. It has to perform some basic analysis to tell the difference between normal operation and a potential problem.

Here’s a quick Python snippet showing how you might publish this kind of data:

import paho.mqtt.client as mqtt
import json # Use JSON for structured data
# Assume 'read_vibration' and 'read_temp' are functions you've built
# to get data from your ADXL345 and DS18B20 sensors.

MQTT_BROKER = "192.168.1.100" # Your factory broker's IP
client = mqtt.Client(client_id="machine-monitor-1")
client.connect(MQTT_BROKER)

vibration_data = read_vibration() # e.g., returns a dictionary {'x': 0.1, 'y': 0.2, 'z': 1.1}
temperature_data = read_temp()   # e.g., returns 55.4

# Create a single JSON payload
payload = {
    "vibration": vibration_data,
    "temperature": temperature_data
}

# Publish a single, structured message
client.publish("factory/machine1/status", json.dumps(payload))

print("Published machine data.")

Once this data is flowing, you can pipe it into a platform like ThingDash, set up dashboards to visualize it, and create alerts that notify you the moment a machine’s temperature exceeds a critical threshold or its vibration signature changes.

The sheer variety of what you can build with a Raspberry Pi and some sensors is incredible. To help put these ideas into perspective, let's compare them side-by-side.

Comparison of Raspberry Pi IoT Use Cases

This table breaks down the different applications we've discussed, highlighting what hardware you'd need, how complex the project is, and the real-world impact you can expect.

As you can see, the complexity scales with the potential impact. A home automation project is a fantastic starting point, while industrial monitoring showcases the Pi's power in a high-stakes environment. Each one, however, is built on the same core principles of sensing, processing, and acting.

Your Questions, Answered

As you start piecing together your first IoT with Raspberry Pi project, you’re bound to hit a few common roadblocks or have some questions pop up. Let's tackle some of the most frequent ones I hear from makers just like you.

Which Raspberry Pi Model Is Best for IoT?

This is probably the most common question, and the answer is always: it depends on the job.

For most projects, I find the Raspberry Pi 4 Model B is the perfect workhorse. It has more than enough processing power to run a local server, juggle data from several sensors, and its dual-band Wi-Fi and Bluetooth 5.0 provide solid, reliable connectivity. It’s my go-to for anything that needs a bit of muscle.

But what if you're building a tiny, battery-powered sensor to tuck away in a corner? That's where the Raspberry Pi Zero 2 W really shines. It's incredibly power-efficient and small, making it a fantastic and cheap option for simple, focused tasks where energy consumption is the name of the game.

My advice? Don't just grab the most powerful Pi. Think about your project's specific needs—power, size, and what you're asking it to do. Matching the model to the mission is the secret to a successful and efficient build.

Can I Run Multiple Sensors on One Raspberry Pi?

Absolutely, and you should! The Raspberry Pi's GPIO header is built for exactly this. You can connect a whole host of sensors at the same time. The real limits are the number of physical GPIO pins you have and whether the Pi can process all the incoming data streams without breaking a sweat.

There are a couple of smart ways to manage this:

• Direct Connections: The simplest method. Just assign each sensor to its own GPIO pin. This works great for a few digital sensors.

• I2C or SPI Protocols: This is the pro move. These communication protocols let multiple devices share the same few wires—just two for I2C or four for SPI. Tons of sensors support these, so you can daisy-chain them without hogging all your GPIO pins.

A classic setup I often use is running a BME280 temperature and humidity sensor on the I2C bus while a PIR motion sensor is connected to its own dedicated GPIO pin. Python libraries make it surprisingly easy to talk to each one independently, all from the same script.

What Is the Difference Between an IoT Gateway and an IoT Device?

Understanding this distinction is fundamental to designing a good IoT system.

Think of an IoT device (or a "node") as a specialist. It’s a single-purpose component out on the front lines. Its job is to do one thing well, like a temperature sensor collecting data or a smart relay turning something on or off.

An IoT gateway is the field commander, a role the Raspberry Pi plays brilliantly. It's a more powerful, central hub that acts as a bridge. It gathers data from all your local IoT devices and then securely communicates with the cloud or your main network. It can also run "edge computing" tasks, processing data right then and there before sending it on, which cuts down on latency and saves a ton of bandwidth.

Do I Need a Cloud Service for My Raspberry Pi IoT Project?

Not always! It really boils down to what you want to achieve. You can build a completely self-contained IoT system that runs entirely on your local network. A perfect example is running a Mosquitto MQTT broker on your Pi to create a private smart home network. Your devices can chat with each other all day long without ever needing to connect to the wider internet.

However, bringing in a cloud service like AWS IoT Core or a dedicated MQTT platform becomes a game-changer when you need to:

• Access your sensor data from anywhere in the world.

• Store massive amounts of historical data for trend analysis.

• Run complex analytics or machine learning models on your data.

• Securely manage and update a large fleet of deployed devices.

The choice is yours: prioritize total privacy and offline reliability with a local-only setup, or opt for global access and powerful data processing with a cloud-connected one.
