Uses for for triggering various vibrations, alarm for theft, smart car, earthquake alarm, motorcycle alarm, etc.
Compared with the normally open vibration sensor module, this module has a longer vibration triggering time and can drive the relay module
- Adopt SW-420 normally closed vibration sensor produced by our company.
- Comparator output, clean signal, good waveform, strong driving ability, over 15mA
- Working voltage 3.3V-5V
- Output form: digital switch output (0 and 1)
- Equipped with fixed bolt holes for easy installation
- Small board PCB size: 3.2cm x 1.4cm
- Use wide voltage LM393 comparator
Penggunaan Modul :
- When the product does not vibrate, the vibrating switch is closed and conducting, the output end outputs low level, and the green indicator light is on;
- When the product vibrates, the vibration switch is momentarily disconnected, the output end outputs a high level, and the green indicator light is off;
- The output terminal can be directly connected to the single-chip microcomputer, and the high- and low-level can be detected by the single-chip microcomputer, thereby detecting whether there is vibration in the environment and playing an alarm role
