Description 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 SPESIFIKASI : 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
