- 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.
What's in the package:- 1 Pcs * SW-420 Motion Sensor
