LM393 Datasheet

When this no vibration, this module output logic LOW the signal indicate LED light,And vice versa.

Application Ideas

  • Vibration detecting
  • Burglary protection system 
  • Object Movement detecting
  • Triggering effect reported theft alarm
  • Smart car
  • Earthquake alarm
  • Motorcycle alarm

Features

  • The default state of the swith is close
  • Digital output Supply voltage:3.3V-5V
  • On-board indicator LED to show the results
  • On-board LM393 chip
  • SW-420 based sensor, normally closed type vibration sensor
  • Dimension of the board: 3.2cm x 1.4cm 

Board Schematic

Use

  • The module does not vibrate, vibrate switch is closed conduction state, the output output low, the green indicator light comes ON.
  • Vibration state, vibration switch instantly disconnect the output output high, the green light is not on;
  • The output is directly connected to the microcontroller to detect high and low, thereby detecting the vibration environment, play an alarm role 

Sensor Details SW-420 

Single-roller type full induction trigger switch. 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. This specification products are completely sealed package, waterproof, dustproof.

Principle
Usually at any angle switch is ON state, by the vibration or movement, the rollers of the conduction current in the switch will produce a movement or vibration, causing the current through the disconnect or the rise of the resistance and trigger circuit. The characteristics of this switch is usually general in the conduction state briefly disconnected resistant to vibration, so it's high sensitivity settings by IC, customers according to their sensitivity requirements for adjustments.
