Check out these inspiring IoT ideas to make Internet of Things projects with your Raspberry Pi.
Launched in 2012, the Raspberry Pi single-board computer has had a lot of different versions since then, from ever more powerful standard credit-card-sized boards to the even smaller Pi Zero and the keyboard-embedded Pi 400.
Around the world, it’s been used for home automation, edge computing, and many Internet of Things (IoT) projects. In this article, we’ll take a closer look at ten impressive IoT projects made with the Raspberry Pi.
1. Smart Video Doorbell
At the heart of this DIY smart doorbell is a Raspberry Pi 3B connected to an LCD display, a camera, STEMMA speaker, and a plug-and-play amplifier.
According to the maker, the software side of things is relatively simple, with only a couple hundred lines of code. As for the video calls, the free encrypted video conferencing app Jitsi Meet was used.
2. Pi Roomba
The Roomba is an autonomous robot vacuum cleaner which takes a random path around the floor. Using a Raspberry Pi, this project makes it smarter.
In this project, a Roomba 530 was used in conjunction with a Raspberry Pi. To connect the two, a serial connection is required, along with a way to power the Raspberry Pi from the 18 volt power supply of the Roomba.
The Roomba was modified to fit a plastic case on top to house the Pi. The case is connected to the Roomba’s bumper; this way, when the Roomba moves under a chair and it catches the case, the force is then transmitted to the bump sensors. The software will then figure out what to do.
3. Sleepbuddy IoT Babysitter
This IoT babysitter is connected to a smartphone, tablet, or computer. You can control all of his emotions, microphone, gestures, speaker, and camera with a button.
There is a hidden camera in the eye to monitor the surroundings and children. The speaker and microphone make it possible to talk to the kids through Wi-Fi. The Sleepbuddy also comes with blackboard paint, so if they fancy doing so, kids can decorate their robot friends with chalk just before bedtime.
4. Raspberry Pi AI Teasmade
If you’re a fan of the Raspberry Pi and enjoy a good cup of tea (it might even work with coffee!!), then this is the project for you. The ‘R2-Tea2’ was designed and built with the focus of creating a robot tea-maker that was a hybrid of a chatbot and a tea maker. Based on the user’s responses in conversation, it decides what kind of tea to make.
There is also AI implemented here which analyses the user’s day to approximate their current stress level. Then, depending on the stress level, it decides what kind of cup to use, which kind of tea to make, how much milk to add, and for how long it should brew the tea!
5. Air Quality Monitor
Build your own home automation system, starting with this indoor air quality monitoring HAT for the Raspberry Pi. The LiV Pi is an expansion board that turns your Raspberry Pi into an indoor air quality monitoring device. Measure the carbon dioxide level, temperature, humidity and, air pressure of your bedroom, greenhouse, garage, or other setting.
The other components for the project include a DHT22 temperature and humidity sensor, a BMP180 air pressure sensor, an LCD display, connection cable, a DS3231 RTC module, a 16GB microSD card, and of course a Raspberry Pi.
6. Smart Energy Monitor
Want a project that monitors both energy use as well as production? If your home has a solar panel or another way to make its own power, this project will help you keep track of how much energy your home uses and how much power it produces too!
The software and hardware are completely open-source and the team has put together in-depth documentation on how you can utilize a Raspberry Pi to create this system. Data is extracted every 0.5 seconds with an MCP3008 ADC coupled to up to six current sensors to offer real-time usage data, displayed using Grafana so you can view all of the information at once.
7. Water Level Monitor
Water level monitoring is used in water treatment applications, such as for pump control and channel flow measurements. Although this simple system works with a bucket of water, it demonstrates this principle, and was was made with a Raspberry Pi 3 Model B, an ultrasonic distance sensor, buzzer, and some jumper wires.
When the distance of the ultrasonic sensor from the water is within the range of 4 centimeters, the buzzer makes a sound, alerting you that the bucket is almost full. You could build a similar project using a special liquid level sensor instead.
8. Smart home bulb
Controlling your lights via the internet has never been easier, thanks to loads of companies now making smart bulbs you can hack. One of the main points of building a smart home is so that you can have a home that’s easier to control and that can react automatically, making your life easier and more convenient. While there are plenty of mainstream systems that do this, from Amazon Alexa to Samsung SmartThings, they rely on giving data to big companies.
With the WebThings Gateway (previously known as Mozilla Things), you can build your own home automation server with a Raspberry Pi.
9. Magic Mirror
A now popular Raspberry Pi project, smart/magic mirrors are an amazing way to make sure you’re ready for the morning.
Whether in the bathroom, closet, or bedroom, chances are you probably use a mirror regularly for tasks like getting ready for the day or trying on new clothes. However, your mirror’s capabilities don’t have to stop at simply reflecting light.
With a Raspberry Pi and a few other components, you can make a customizable smart mirror that projects a computer display over a traditional reflective mirror. Some possible uses include displaying the time, a calendar, picture, or other applications in your reflection. These features can help make you more productive or simply allow you to integrate more smart tools into your home.
A Raspberry Pi smart mirror combines a reflective display with customized features.
10. Raspberry Pi Powered IoT Garden
A smart garden checks on the plants’ environment to ensure the optimal conditions for them to grow. This project automatically waters plants when the soil is dry. It even turns on the lights when it gets too dark.
A Raspberry Pi is used with a Grove Pi+ board to collect data from the sensors as well as operating various actuators. The air humidity, temperature, and brightness levels in the area are recorded, as is soil moisture. Users can monitor these values when they check on their plants via a custom smartphone app.
