Detail about SW-420 Motion/Vibration Switch Sensor Module

The Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer. 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. When this no vibration, this module output logic LOW the signal indicate LED light, And vice versa.

This product is single-roller type full induction trigger switch, this product can be a full production induction direction of vibration, tilt. 2. When no vibration or tilt, the product is on conduction state, and in the steady state, when a vibration or tilt, the switch will be rendered instantly disconnect the conductive resistance increases, generating a current pulse signal, thereby triggering circuit. 3. This specification products are completely sealed package, waterproof, dust proof.

The product is suitable for the small current circuit specifications tilt, vibration sensors vibration sensor is triggered, the alarm on the electric car, motorcycle, also can be used for the development of scm application. Because it briefly the buzz film used in the conventional alarm device, the complex structure of the magnet plus the spring, and thus on the electric car alarm in recent years extensive application.

Application Idea

Vibration detecting
Burglary protection system

Features

On-board indicator LED to show the results
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

Usage

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
