We have built a system for tracking the various condition of a car and sending the information remotely. Basically, it is like a black-box of an aero-plane which is used for the purpose of facilitating the investigation of accidents and incidents. Using raspberry pi, arduino with shield , accelerometer , an usb camera and python.
When your car gets crashed, the accelerometer value changes by high number. This situation alerts the system to take pictures and videos which are then send to customer and customer's emergency contacts by the insurance company. I hope this system helps the insurance company to provide better customer experiences.
