KY-020 Tilt Switch Sensor module
KY-020 tilt switch sensor module with digital output—ideal for tilt detection, alarms, robotics, and DIY electronics projects.
The KY-020 Tilt Switch Sensor Module is a simple and effective sensor used to detect orientation or tilting. It features a reed switch inside a cylindrical casing that closes or opens the circuit when the module is tilted beyond a certain angle.
The module provides a digital output that can be directly interfaced with microcontrollers such as Arduino, ESP32, ESP8266, Raspberry Pi, and STM32. It operates on a wide voltage range and is easy to integrate into projects requiring motion or tilt detection.
Common applications include tilt alarms, orientation detection, robotics, anti-theft systems, and interactive DIY electronics projects. Its compact size, low cost, and ease of use make it ideal for both beginners and professionals.
