The KY-017 Mercury Tilt Switch module is a switch that responds to movement. It uses a small mercury ball that completes the circuit when the module is tilted.

Compatible with many electronics platforms like Arduino, Raspberry Pi, ESP32 and others. For less sensitive tilt detection use the KY-020 tilt switch.

KY-017 SPECIFICATIONS

This module consists of a mercury switch, a 680Ω resistor and a LED that will light up when tilt is detected. The mercury ball will open/close the circuit when the module is rotated.
