Specifications Tilt sensor consists of 3 pins : GND, VCC, DO (Output Signal) Operating Voltage : 3.3 V to 5 V Maximum output current : 15mA Working Not Tilted When the sensor is in “Not Tilted” position, the mercury ball will be at the bottom and shorting the contacts as shown in the image below. This will turn ON the LED and the output will be LOW. Tilted When the sensor is in “Tilted” position, the mercury ball will move away from the contacts as shown in the image below. This will turn OFF the LED and the output will be HIGH. Circuit Diagram Mercury Switch Module Ky-017 Sensor In Pakistan 4 Description The GND pin of tilt sensor – GND pin of Arduino Uno.
