SW-520D Tilt Sensor Module Digital Output

The SW-520D Tilt Sensor Module is an orientation detection device that uses a ball switch mechanism combined with an LM393 comparator to provide a stable digital output. It operates within a voltage range of 3.3–5 V and delivers a clean 0/1 signal with reliable switching performance. The module features a high-sensitivity SW-520D sensor capable of detecting changes in angle and motion, making it suitable for position sensing applications. Its onboard comparator ensures consistent waveform output and supports driving currents above 15 mA. The module is compatible with microcontrollers such as Arduino and other embedded systems, and includes mounting holes for straightforward integration into electronic projects.
