5PCS Vibration Sensor Module SW-420 Alarm Switch DIY Normally Closed High Sensitive Efficient Module for Arduino
Product Description
5PCS Vibration Sensor Module SW-420 Alarm Switch DIY Normally Closed High Sensitive Efficient Module for Arduino
Condition: New
SW-420 Motion Sensor Module
The company produced normally closed type vibration sensor SW-420
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
Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit
Product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright
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 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
Package included:
5 pcs Normally Closed Alarm Vibration Sensor Module Vibration Switch SW-420
