Ky-020 Tilt Switch Sensor Module

The KY-020 Tilt Switch Sensor Module is a simple and reliable motion-activated switch designed to detect changes in orientation or position. It uses a ball-bearing metal switch that closes or opens the circuit when tilted beyond a certain angle, providing a digital HIGH or LOW signal output. Compact and easy to use, this module operates on 3.3V–5V, making it fully compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers. It’s perfect for motion detection, anti-theft systems, angle sensing, and robotics applications.
