High Quality SW-420 Normally Closed Alarm Vibration Sensor Module Vibration Switch SW420
Click Image for Gallery
For a variety of shocks triggering, theft alarm, smart car, an earthquake alarm, motorcycle alarm.
This module when compared with normally open penumatic shock sensor module, shock triggered much longer can drive relay module
1, the use of the company's production of SW-420 normally closed type vibration sensors.
2, comparator output signal clean wave well, driving ability, 15mA
3, rated voltage and 3.3V-5V
4, output: digital switching output (0 and 1)
5, a bolt-hole for easy installation
6, small Board PCB dimensions: 3.2cm x 1.4cm
7, using wide LM393 voltage comparator
1, the product when it is not shock, vibrate switch is closed on-State, output output low level, the green indicator light is on;
When 2, vibration, vibration switches disconnected moments, output output line, the Green led is not lit;
3, the output can be directly connected to the microcontroller, by single-chip computer to detect high or low level, to detect whether there is vibration, alarm function
