It can be used to trigger the effect of various vibration, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc.
This module is compared with the normally open type vibration sensor module, vibration trigger for longer periods of time, can drive the relay module.
1) Using SW-420 normally closed type vibration sensor
2) Comparator output- clean signal- good waveform- strong driving ability- >15mA
3) Working voltage 3.3V ~ 5V
4) Output format: digital switching output (0 and 1)
5) Using a wide voltage LM393 comparator
6) With bolt holes for easy installation
7) Small PCB size: 3.2 x 1.4cm
1) Various vibrations trigger: Arduino- Smart car- Earthquake alarm- Motorcycle Alarm- Theft alarm
