KY-002 Vibration Tilt Sensor module is ideally suited to adding knock sensing to your project.
This is a knock detection module which can detect a percussion based event to trigger a switch like response.
The vibration switch consists of a fine spring within a metal cylinder when the module is vibrated to a sufficient amount, the spring will touch the walls completing the circuit.
Once connected a LOW signal will be returned on the S pin.
