เซ็นเซอร์วัดการสั่น Vibration sensor module normally closed Alarm sensor module Vibration Switch SW-420

product description :

For a variety of vibration triggering, reported theft alarm, intelligent car, earthquake alarm, motorcycle alarm.
This module normally open with shock sensor module compared to shock triggered longer can drive relay module

Module Features:
1, the use of the company's SW-420 normally closed vibration sensor.
2, the comparator output signals clean, good waveform, driving ability, than 15mA
3, the working voltage of 3.3V-5V
4, the output form: digital switching output (0 and 1)
5, a fixed bolt hole for easy installation
6, small PCB board size: 3.2cm x 1.4cm
7, using a wide voltage comparator LM393

Module Description:

1, when the product does not shock, vibration switch was closed conductive state, output of low output, the green indicator light;
2, when the product is shock, vibration switch off instantly, output terminal output high, the green light does not shine;
3, the output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting whether the environment there is vibration, play a role in the police
