The KY-017 Mercury Tilt Switch Module is a compact, high-sensitivity sensor that uses a mercury ball to detect tilt or movement. When tilted, the mercury completes the circuit, triggering an LED indicator. Ideal for Arduino, ESP32, and Raspberry Pi projects, it operates at 3.2V-5V DC and provides reliable tilt sensing for DIY electronics and prototyping.
