The vibration sensor is based on the high precision vibration sensor 801S, it has 2 outputs: the TTL and analog output. The sensitivity of TTL output can be adjusted by the on-board potentiometer, you can also read the analog output with any ADC to get the vibration condition.
This vibration sensor module is compatible with any microcontroller that has digital input. Of course, popular microcontrollers such and PIC and Arduino has digital input and thus they are compatible. The direct interface is essential to use this sensor.
Pin Assignments:
- Aout = Analog Output
- – = GND
- Dout = Digital Output
- + = VCC, 5VDC
