The SW-520D Tilt Sensor Module is a simple and reliable angle/tilt detection sensor that uses a rolling metal ball inside to detect orientation changes. When the sensor is tilted beyond a certain angle, the internal ball closes the circuit, producing a digital output signal. It is widely used in orientation detection, safety alarms, robotics, and DIY Arduino projects.
