SW-420 Motion Sensor Module Alarm Vibration Switch ***LOCAL STOCK***

- Working voltage of 3.3V to 5V

- Output form: digital switch output (0 and 1)

- Has fixed bolt holes, convenient installation

- small board PCB size: 3.2cm x 1.4cm

- Uses the LM393 wide voltage comparator

 

 

 

Module directions for use:

1, No vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit;

2, Vibration, the vibration switch instantaneous disconnection, output the high level, the green light is not on;

3, Output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect whether there is vibration.
