🌐 The SW-520D is a simple mechanical vibration sensor that functions as a switch. When subjected to vibration or tilt, a small internal metal ball completes the circuit, sending a digital ON/OFF signal. It’s perfect for motion detection, anti-theft alarms, or basic interaction triggers in Arduino and ESP32 projects.
