Crash Collision Sensor Switch Module for Robot Model RC car Drones Quadcopter Arduino (Blue)

Collision Sensors can detect whether any collision movement or vibration happens. It will output a low pulse signal when vibration is detected. To make the output signal more reliable and neat, we added a necessary exterior circuit to reduce the noise impact. So, normal shaking will not cause any output. The sensor has a high sensitivity, then you can use it to apply to your projects, such as automatic wake-up and power-down for battery management.

• If a collision happens upfront of where the collision module is installed, the module outputs a low-level signal; no collision outputs a high-level signal.

• Module reserves M3 mounting hole, convenient for fixation on a car.

• With switch indicator light, if there is a collision, light is on; no collision, light is out.

• Pin definition: 1 + 3v-12v power supply, 2 - GND, 3 S Gigh-low level output
