3pin Percussion Knocking Knock Sensor Module

The Tap sensor module is a piezoelectric device, which creates an electrical signal when mechanically deformed by a tap or knock, is commonly used as the sensor. The sensor module most likely contains the piezoelectric element as well as extra circuitry to amplify and condition the piezoelectric element’s output signal. The sensor’s output can be a digital signal, such as a change in voltage level or a pulse, that can be read by a microcontroller or other device. These sensors have a wide range of applications, including security systems, human-machine interfaces, and toys, where the detection of a tap or knock is required. Knock sensor module and a digital 13 interface, built-in LED build a simple circuit to produce percussion flasher. Interface comes with digital LED, will knock sensor connected digital 3 interface, when percussion sensor senses measure to percussive signals, LED flashing light.
