Arduino KY-017 Mercury open optical module

Mercury tilt switch that allows you to detect the tilt of your object.
Module also contains a status led.

One bad thing about this module is the toxic mercury.

As long as the glass bulb is closed it will give no problems.
This module needs to be disposed as toxic waste !

Hardware

• S           Arduino Pin 3
• middle   +5V
• -           GND

Function

Arduino led (Pin 13) displays tilt status.
