Using a Raspberry Pi Zero as an IoT platform for your car
Internet of Things is the new hot in tech
Internet of Things (IoT) is a popular buzzword in the tech/gadget community. The concept is that all the devices in our everyday life can be online/connected to the Internet 24/7, and thereby help to improve and make our lives more efficient. This includes our light bulbs, kitchen appliances, TVs, alarm and heating systems etc. All our "things" should be able to communicate with each other and be controlled from everywhere in order to achieve a more efficient and convenient world for us to live in.
Ideas for the connected car
Why should it not also include your car? Major tech companies have already started a built-up within this field, such as Tesla, Google and Uber. But where does that leave us, who cannot afford an expensive luxury car with the latest tech gadgets or a Tesla with an autopilot?
Different attempts to solve this have been made earlier. Most attempts have been made using the OBD port of the car, and thus reading out telematics from the CAN bus of the car. Common for all these previous systems is that their platform was locked for modifications and alterations by the users.
This puzzled us and we decided to try to build our own system. We wanted a system that everybody could change, update and modify to their likings. We wanted a system that was always online and available. We did not want a system that was dependent on an internet connection through a mobile phone. We wanted a true IoT platform in the car.
Our requirements was:
- Online even when friends or family members use the car
- Not dependent on a mobile phone
- Open for programmable changes
- But also configurable without programming experience
- Extensible with external systems
- Built on a well known hardware platform
An IoT platform built on the Raspberry Pi Zero
We quickly realized that the products from The Raspberry Foundation was very suitable for our project. We ended up deciding to use the Raspberry Pi Zero as the heart of our hardware dongle. The Raspberry Pi is a widely used, affordable and proven micro computer. It runs a high-level operation system and has a large backing community.
We decided to build a HAT (Hardware Attached on Top) for the Raspberry Pi Zero, containing the needed IOs.
- 4G LTE modem
- USB connectors
- OBD connection to the car
- GPS + A-GPS
- Wireless LAN
- HDMI port
A software platform built for IoT
We created a hardware platform that matched our initial requirements, but our vision was not complete. We wanted to connect our car and hardware dongle to an IoT software platform, from where we could easily manage and update the entire system. We wanted the platform to include a fully customizable dashboard, where each user could set up their own widgets.
We wanted it to be easy to install new features from a community driven platform:
But we wanted to make sure that the user still had full possibility to interact, configure and program their Raspberry Pi and car directly from our IoT Platform:
A more detailed overview of the AutoPi IoT platform can be seen HERE
- The AutoPi is not dependent on a connection to a mobile phone and is therefor online no matter who is driving the car
- Advanced code modules can be programmed, uploaded and tested directly from the built-in editor.
- Dashboard, triggers and add-ons are available for easy configuration and does not require programming experience.
- With built-in WiFi, Bluetooth and USB it is easy to extend the system with other subsystems and extend the possibilities of the system.
We ended up with an open and versatile system with some unique key features:

Speak to your car (almost) like K.I.T.T. from Knight Rider
Wouldn’t it be cool if you could speak to your car and give it commands? We remember our childhood in the last millennium where Michael Knight (David Hasselhoff) and his intelligent Pontiac Trans Am named K.I.T.T. solved crime together. While we may not be able to have a meaningful conversation with our car just yet, it’s now a possibility to talk to your car and give it commands to execute. We are here giving a short introduction to how this can be accomplished using the AutoPi.io system and Google Assistant.
How to easily add remote theft detection to your car
Your car is a valuable and expensive asset. Even with full insurance a car theft can be a cumbersome and expensive affair. But how can you help prevent theft of your car and possibly avoid an increased insurance premium? In this blog post, we explorer the possibilities to get remote theft detection, using the AutoPi platform.
What is AutoPi and What Does It Do?
Get a short introduction to how AutoPi works and what it does for you. We will cover some of the technical details but also give a brief overview of the use case scenarios for this IoT device, like theft detection and remote safety monitoring.
