SW420 Vibration or Shock sensor module

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. The output can connect 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.

Using SW-420 normally closed type vibration sensor.

The comparator output signal is clean, good waveform, driving ability, more than 15Ma

The working voltage of 3.3V-5V

The output format: digital switching outputs (0 and 1)

A fixed bolt holes for easy installation

Small PCB board size : 3.2cm x 1.4cm

Using a wide voltage LM393 comparator
