KY-017 Mercury Tilt Switch Module

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. 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. Compatible with many electronics platforms like Arduino, Raspberry Pi, ESP32 and others. This KY017 Tilt Switch Sensor Module measures the orientation and if the orientation goes beyond a certain level it lights up an LED on the module and gives out a digital signal on the signal Pin which can be used to read by the Arduino or Raspberry Pi or any development board you are using by taking input on any of the GPIO pins on offer. The mercury ball in the glass envelop will either open or close the circuit with different orientations. It is small in size, economic and very easy to interface with any of the microcontroller you are using.
