Tilt Sensor Module SW520D

The Tilt Sensor Module SW520D uses a cylindrical SW520D tilt switch that contains a small conductive ball which moves inside the sealed tube. When the module is tilted or shaken, the ball shifts position, making or breaking electrical contact that produces a digital HIGH or LOW output. This output can be directly interfaced with microcontrollers such as Arduino, ESP, STM, and Raspberry Pi.

The module includes a signal conditioning circuit with a resistor network and status LED for instant visual indication. It operates stably under low power and is ideal for simple motion, vibration, anti-theft, and orientation-based detection in automation, robotics, smart electronics, and safety devices.
