The SW-420 Vibration Sensor Module also known as Shock Sensor Module is a small, easy-to-use sensor that can use to detect vibrations. SW-420 is based on the SW-420 vibration sensor, which works on the principle that when the movement or vibration occurs, the circuit will be briefly disconnected and output low.

Shock Sensor Module/SW-420 Vibration Sensor Module can operate with an input voltage of 3.3V to 5V DC. This makes it compatible with a wide range of devices, including Arduino, Raspberry Pi, and other microcontrollers.

The sensitivity of the SW-420 Vibration Sensor Module can adjust using the onboard potentiometer. The potentiometer controls the threshold voltage of the LM393 comparator IC. By adjusting the potentiometer, you can change the amount of vibration that is required to generate a logic high signal.
The SW420 Vibration Sensor Module works on the principle that when the movement or vibration occurs, the circuit will be briefly disconnected and output low. Hence the normal state of this sensor close.

The SW420 Vibration Sensor Module is based on the SW-420 vibration sensor, which is a piezoelectric sensor. Piezoelectric sensors generate an electrical charge when they are subjected to mechanical stress. In the case of the SW-420 Vibration Sensor Module, the mechanical stress is caused by vibrations.

The logic high signal from the LM393 comparator IC is then output by the SW-420 Vibration Sensor Module. The logic high signal can use to trigger an alarm, control a device, or log the occurrence of a vibration.

Features : –

The electrical charge generated by the SW420 Vibration Sensor Module is amplified by the LM393 comparator IC. The LM393 comparator IC compares the amplified electrical charge to a threshold voltage. If the amplified electrical charge is greater than the threshold voltage, the LM393 comparator IC will output a logic high signal. If the amplified electrical charge is less than the threshold voltage, the LM393 comparator IC will output a logic low signal.

SW-420 Vibration Sensor Module has a number of features, including:

High sensitivity
Wide operating voltage range
Adjustable threshold
Small size and easy to use
