The sensor works with the help of switch which give system touch effect so that it can be used as a touch sensor. Bump sensor can work the platform like arduino, pic, and 8051 etc. bump sensor comes with 3 pin with output ,vcc and ground .
Provides precise, contact distance protection within a 2 cm to 3 cm range.
Bump sensor work as non-proximity sensor.
Simple to use for the distance protection of the robot before it collide with obstacle.
It is having SPST switches which give the signal in 0or 1ie digital condition.
3-pin header makes it easy to connect to a development board, directly or with an extension cable, no soldering required.
