Hello i just want to ask you that whether the Piezo electric disc "knock sensor" can detect accident in the car. because i know that it can detect sound and vibration... what i need is to detect the pressure, is it suitable for detecting high level of impacts ?? thanks :slight_smile:

Accelerometer should be fine, why do you need to use other sensors ?
