Module instructions:

1. When the product is not vibrating, the vibrating switch is closed and conducting, the output terminal outputs low level, and the green indicator light is on;

2. When the product vibrates, the vibration switch is disconnected, the output terminal outputs a high level, and the green indicator light is off;

3. The output terminal can be directly connected to the single-chip microcomputer, through the single-chip microcomputer to detect high and low levels, thereby detecting whether there is vibration in the environment, and acting as an alarm

Package includes:

1 X SW-420 Vibration Sensor Module
