Vibration Sensor Module SW-420

Vibration sensor. Used for vibration detection in anti-theft systems, burglar alarms and even for earthquake detection.

There are two LEDs on the module body. Red is connected to the power pin and lights up when the module is powered. Green is connected to a digital output and is lit when the sensor is triggered. The sensitivity of the sensor is regulated by a trimming resistor located on the board. At the output D0 there is a logical 1 if there is no operation and a logical 0 if the sensor is activated.

Specifications:

output: digital
Has a mounting hole for mounting
board dimensions: 3.2x1.4 cm
LM393 is used as a comparator.
