Hello,

i caught with different types of accelerometer sensors

Hello all,

Currently i am working on a project My project deals with accelerometer sensor for motion or movement detection

Project:

I would like to place the acceleormeter sensor under the Road Curb Ramp Speed Breaker (Speed bumps or speed breakers are the common name for a family of traffic calming devices that use vertical deflection to slow motor-vehicle traffic in order to improve safety conditions.) to detect if a vehicle is moving or passing above the road curb the accelerometer must react and communicate with raspberry pi to trigger an alaram or to trigger the camera

could some one help me in giving any sort of inputs to get the cheap and best sensor
