Mercury Switch Module KY017

English Version

Product Overview
The Mercury Switch Module KY-017 is a tilt-sensing module designed for detecting orientation changes in automation, security, and robotics projects. It uses a mercury tilt switch to trigger a digital signal when tilted, making it ideal for motion-activated alarms, anti-theft systems, and educational experiments. Compatible with 3.3V/5V microcontrollers like Arduino and Raspberry Pi, this module offers a simple and reliable way to detect angular movement.
