In this video I am going through a KY-031 Knock Sensor module it is a vibration sensor that sends a signal when a knock/tap is detected

This can be connected to most microcontrollers such as Arduino, RaspberryPi, ESP32, ESP8266 ect.

KY-031 KNOCK SENSOR MODULE Specifications
-----------------------
This module consists of a spring-based sensor, a 10 kΩ resistor and 3 male header pins. The spring emits a high signal when a vibration is detected.

Operating Voltage: 3.3V ~ 5V
Output Type: Digital
