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

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.

Board Schematic

Vibration-Sensor-Module6

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
