SW-420 Motion Sensor Module Alarm Sensor Module Vibration Switch / new normally closed type vibration sensor module alarm sensor module vibration switch SW - 420

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:      the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma     

the working voltage of 3.3V to 5V      output form: digital switch output (0 and 1)      has a fixed bolt hole, convenient installation     

small board PCB size: 3.2cm x 1.4cm     

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

 

package:

1 Pcs * SW-420 Motion Sensor
