This is  a Car Crash Detector,which warns a relative/friend/family member linked with user of device.The number of users guardian is stored on IFTTT . As soon as the sensors detect a crash or there is any damage to vehicle.

Observe that as soon as i hit the car(on the sensor with the ball),a message is sent to my mobile number(the one i have registered on IFTTT).

NOTE:Threshold for damage is set as per toy setup.

I have not added the location functionality with this,but can be easily obtained using a GPS sensor.

This project is carried out using Arduino and ESP-01.
