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 onboard potentiometer.

When this no vibration, this module output logic LOW the signal indicates LED light, and vice versa.
If the module does not vibrate, the vibration switch was closed on state, the output of low output, the green indicator light. The product vibrates, vibration switches momentary disconnect, the output is driven high, the green light does not shine.

The output can be directly connected to the microcontroller, which to detect high and low level, so as to detect whether the environment exists vibration, play a role in the alarm.

Application Idea

It is useful for a variety of shocks triggering, theft alarm, smart car, an earthquake alarm, motorcycle alarm. This module when compared with a normally open pneumatic shock sensor module, shock triggered much longer can drive the relay module the use of the company’s production of SW-420 normally closed type vibration sensors. comparator output signal clean wave well, driving ability, 15mA rated voltage and 3.3V-5V output: digital switching output (0 and 1) a bolt-hole for easy installation small Board PCB dimensions: 3.2cm x 1.4cm. using the wide LM393 voltage comparator.

Features

  • The default state of the switch is closed.
  • Digital output
  • Supply voltage:3.3V-5V
  • On-board indicator LED to show the results
