For a variety of vibration the triggering effect reported theft alarm, smart car, earthquake alarm, motorcycle alarm.
Compared with normally open type vibration sensor module, it has longer trigger vibration time, can drive relay module.

Module Features:
1, SW-420 using normally closed type vibration sensor.
2, the comparator output, the signal is clean, good waveform, strong driving ability, exceed 15mAh
3, operating voltage 3.3V-5V
4, Output form: Digital switching output (0 and 1)
5, a fixed bolt hole for easy installation
6 small board PCB size: 3.2cm*1.4cm
7, Wide voltage LM393 comparator

Instructions:
1, When the product does not vibrate, vibrate switch will be in closed conduction state, the output terminal output low level and the green indicator light will be on;
2, When the product vibrates, vibration switch will instantly disconnect, the output terminal output high level and the green light will not be on;
3, The output terminal can be directly connected to the microcontroller, with the microcontroller to detect high and low level, thereby detecting the vibration environment, play an alarm role.
