SW-420 Normally Closed Vibration Sensor Module for Alarm System Smart Vehicle Robot Helicopter Airplane Aeroplane Boart Car

Product Description:

Module Features:
1, the use of the company’s SW-420 normally closed vibration sensor.
2, the comparator output, the signal clean, good waveform, driveability, more than 15mA
3, the working voltage of 3.3V-5V
4, the output form: digital switch output (0 and 1)
5, with a fixed bolt hole, easy to install
6, small board PCB size: 3.2cm x 1.4cm
7, using a wide voltage LM393 comparator

Module instructions:
1, the product does not shake, the vibration switch was closed conduction state, the output low, green light;
2, the product vibration, the vibration switch instantly open, the output high, the green light does not light;
3, the output can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, which to detect whether the environmental vibration, play a warning role

use:
For a variety of vibration triggers, reported Pao alarm, intelligent car, earthquake alarm, motorcycle alarm, and so on.
Compared with the normally open vibration sensor module, the vibration trigger time is longer, you can drive the relay module
