Raspberry Pi Pico detects crashes and sends help


Develop projects on the Raspberry pie comes with its fair share of obstacles, but what if you could watch for disasters along the way? SVS Embedded has put together a project designed to do just that with their Pico-powered Vehicle Crash Detection Kit.

This is one of the many projects developed by the team of Integrated SVS. If you’ve never heard of them, they specialize in creating microelectronics projects for students and offer kits with everything you need to recreate them at home. We recently covered their Raspberry Pi Pico attendance system which uses an RFID sensor to verify the identity of the user.

This project uses a Pico with a GPS module, accelerometer, alcohol sensor and cellular module to detect accidents and send an SMS notification for help. In the demo video, the project is demonstrated using a small robotic car with motors also controlled by the Pico. The project is a proof of concept, to show how a Raspberry Pi Pico and the components can be used to create a potentially life-saving device. The project could be easily integrated into a real vehicle.

SVS Embedded lists everything you need to recreate this project which includes a 16×2 LCD screen, a GY-GPS6MV2 GPS module, an MQ3 alcohol sensor, an L293D motor controller for the wheels, an ADXL MEMS accelerometer and a module GSM cell phone SIM800L. Some of these components are non-critical and can be swapped out or omitted as needed, but all are a great example of what can go into a crash detection system.

In this project, the Pico checks status information from each of the modules to determine if alcohol levels have increased or not or if the vehicle has spun due to an accident. If the system determines that any of these factors have changed, it uses the cellular module to send an SMS notification with the suspected cause of the crash along with exact coordinate data using the GPS module.

If you want to build this Raspberry Pi project yourself, check out the SVS kit website for more details and options to purchase a kit with all components ready to use. Alternatively, you can check out the video breakdown at Youtube and order a whole piece at a time. Be sure to follow SVS Embedded for more creative Pi-powered microelectronics projects.
