KY-017 Mercury Tilt Switch Sensor Module (3.3V-5V Digital Tilt & Motion Detection Module)

The KY-017 Mercury Tilt Switch Sensor Module is a compact digital sensor designed to detect tilt, orientation changes, and motion using a sealed mercury switch. When the module is tilted beyond a certain angle, the mercury inside the sealed switch flows to make or break electrical contact, generating a digital output signal that can be read directly by Arduino, ESP32, ESP8266, STM32, Raspberry Pi (with suitable interfacing), and other microcontroller platforms. Its simple design and low power consumption make it suitable for tilt detection, motion-triggered alarms, orientation sensing, and educational electronics projects.
