SW-420 Motion Sensor Module Alarm Sensor Module Vibration Switch
Description:
Purpose:
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
Module features:
1, the company produced normally closed type vibration sensor
SW-420,.
2, the comparator output, signal clean, good waveform, driving
ability is strong, for more than 15 ma
3, the working voltage of 3.3V to 5V
4, output form: digital switch output (0 and 1)
5, has a fixed bolt hole, convenient installation
6, small board PCB size: 3.2cm x 1.4cm
7, use the LM393 wide voltage comparator
Module directions for use:
1, product no vibration, vibration switch is closed on state, the
output terminal output low level, the green light is lit;
2, product vibration, the vibration switch instantaneous
disconnection, output the output high level, the green light is not
bright;
3, output can be directly connected to microcontroller, through
single chip microcomputer to detect the high and low level, thus to
detect whether there is a vibration environment, call the police.
