The Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration beyond the threshold. The threshold can be adjusted by the on-board potentiometer.

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

Features:

  • Digital output
  • On-board indicator LED to show the results
  • Supply voltage: 3.3 V-5 V
  • On-board LM393 chip
  • Dimension of the board: 3.2 cm x 1.4 cm

 

LM393 IC

LM393 Comparator IC is used as a voltage comparator in this vibration sensor module. Pin 2 of LM393 is connected to Preset (10KΩ Pot) while pin 3 is connected to vibration sensor. The comparator IC will compare the threshold voltage set using the preset (pin2) and the Vibration Sensor pin (pin3).

Preset (Trimmer pot)

Using the onboard preset, you can adjust the threshold (sensitivity) of the digital output.

SW-420 Vibration Switch

Vibration switch recognizes the amplitude of the vibration to which it is exposed. The switch response can be electrical contact closure or contact opening. The electrical contact may be either an electromechanical relay or a solid-state device.

Using the Vibration sensor module with the microcontroller is very easy. Connect the Digital Output pin of the module to the Digital pin of Microcontroller. Connect VCC and GND pins to 5V and GND pins of Microcontroller.
