YL-99 Switch Crash Collision Sensor Module for Arduino

The Impact Switch Collision Switch Sensor Module for Arduino is leading installation module of the collision. This is low output module, no high output clash. M3 License Module Easy fix hole, small car fix. With the power switch, there is a collision, fire, no lightning bumps. It is used for detecting the collision. Therefore it can also be called a collision signal sensor. Due to different collision direction. The crash switch can turn mechanical quantity to electricity

- Module size: 2.5cm * 1.9cm.
- with a light switch, there is a collision, lights, no collision lights out.
- VCC:  3v-12v power supply
- GND:  then the power ground
- OUT:  high and low output
