The knock sensor is mainly composed of SW-280 vibration switch, which is an inductive proximity switch.It is an electronic switch that transmits the sensing result to the circuit device and induces the circuit to start working when the vibration force is induced.The module comes with a positioning hole for you to fix it to other devices.
You can make full use of it with creative thinking, like electronic drum, and so on.
This module should be used together with EASY plug control board.
