The Vibration Switch Module KY-002 detects shaking and knocking. When the module is moved, a spring mechanism will close the circuit sending a short high signal.
This module consists of a conductive spring, a 10k resistor, and 3 male header pins. Knocking or shaking the module will cause the spring to momentarily close the circuit.
It can be used with a variety of microcontrollers like Arduino, ESP32, Raspberry Pi and others.
CONNECTION DIAGRAM
Connect the module signal pin (S) to pin 3 on the Arduino.
Then connect the module’s power pin (middle) and ground (-) to +5V and GND on the Arduino respectively.
