Product Overview

A knock sensor can monitor whether an object has been hit. A typical knock sensor consists of an organic glass shell and an internal spring, which can sense small amplitude vibrations. Using a knock sensor module, it can be used to create a flashing device, monitor knocking doors, and more.

A vibration sensor is a simple device with a fixed wire inside the tube, surrounded by another thinner wire in a spiral shape.

It can be imagined as a spring with a wire next to it. When there is no vibration, the two wires will not touch each other. Once vibration occurs, the two wires will be short circuited. Therefore, it is necessary to determine whether the wire is short circuited to know if vibration has occurred.
