Tilt Sensor SW-520D Module for Arduino

The Tilt Sensor SW-520D Module is a reliable and affordable motion detection device designed for detecting vibration, tilt, or orientation changes. Based on the SW-520D ball switch, it works by closing or opening the circuit when tilted, providing a clean digital output signal (HIGH/LOW) that can be easily read by Arduino, ESP32, STM32, and Raspberry Pi.

This module is widely used in anti-theft alarms, motion-activated systems, robot balance control, and DIY electronic projects. The built-in comparator circuit ensures a stable output even in noisy environments, and the onboard LED indicator allows you to easily visualize sensor activity.

Compact, durable, and simple to use — the SW-520D tilt sensor module is perfect for beginners and professionals looking for an efficient way to detect motion or orientation changes in their projects.
