Description:

• Collision sensor, also known as electronic switch, is a digital on-off input module necessary for elementary electronic learning.
• By programming, it can realize control over light, sound device, key choice function of LCD display etc.
• Using 3P sensor cable to connect it to sensor shield, it can be installed to 4WD AL alloy mobile robot platform to realize collision detection function.
• It is both convenient and effecient.

Specification:

• If collision happens upfront of where collision module is installed, module outputs low level signal; no collision, outputs high level signal.
• Module reserves M3 mounting hole, convenient for fixation on a car.
• Module size: Approx. 3.7*2*0.9cm / 1.46*0.79*0.35inch
• With switch indicator light, if there is collision, light is on; no collision, light is out.
• Material: FR4 Epoxy Glass Fiber

Pin definition:

• +Pin: 3v-12v power supply  
• - Pin: GND  
• S pin: Gigh-low level signal output

Package Includes:

• 1 x Crash sensor

Note:

• You can make a collision flasher using collision module and built-in LED on interface 13. Connect the collision senser to pin 3, when the collision sensor senses a collision signal, the LEDs on mainboard and module will light up simultaneously.
