SW520D Tilt Sensor Module

The SW520D Tilt Sensor Module is a high-performance, compact module designed to detect tilt, vibration, angular movement, and motion with a digital HIGH/LOW output. It uses a mechanical vibration ball switch inside, which closes or opens a circuit when the module is tilted beyond a certain threshold angle. The module is ideal for Arduino (https://electroway.org/product-category/arduino-and-accessories/arduino-boards/), NodeMcu (https://electroway.org/product-category/iot-and-smart-solutions/iot-modules/nodemcu/), or Raspberry Pi (https://electroway.org/product-category/electronic-accessories/mounts-and-cases/raspberry-pi-mounts-and-cases/) projects that require motion or orientation sensing.

Its small footprint and robust design allow it to be integrated into security systems, robotics, automation devices, IoT gadgets, and DIY electronics projects. The module is lightweight yet durable, capable of handling repeated mechanical movements without losing sensitivity or accuracy.
