Keyestudio Knock Sensor Module compatible with Arduino
The Keyestudio Knock Sensor Module is a piezoelectric vibration sensor designed for Arduino and other 5V microcontrollers (Raspberry Pi, ESP32). It outputs a digital signal upon detecting a physical knock or tap, enabling motion-based input for interactive projects.
Features
- Piezoelectric element detects physical knocks and vibrations
- Digital output signal compatible with 5V microcontroller GPIO
- Simple plug-and-play interface for Arduino, Raspberry Pi, and ESP32
- Compact PCB module with integrated signal conditioning
- Low-power operation suitable for portable and DIY applications

This module utilizes a piezoelectric sensing element that generates a voltage differential when subjected to mechanical stress from a knock or vibration. The onboard circuitry conditions this signal and outputs a clean digital pulse, making it directly readable by a microcontroller’s digital input pin.
Designed for maker and prototyping environments, the module operates on a standard 5V DC supply and is compatible with 5V and 3.3V logic systems, though the output is a 5V digital signal. Its compact form factor and simple three-pin interface (VCC, GND, SIG) facilitate rapid integration into interactive electronic projects, from simple input triggers to complex instrument interfaces.
