Collision Sensor 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. You can use it to apply to your project, such as automatic wake-up and power-down for battery management.
Its working voltage is 5V which makes it compatible with standard Arduino/Seeeduino 5V system.
- Voltage: 3.⅗V
