SPECIFICATIONS

Mercury Tilt Switch Module

The mercury tilt switch module uses a small mercury ball that completes the circuit when you tilt the module. It consists of a mercury switch, a 680 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.

• Operating Voltage: 3.3V to 5.5V

WORKING

Welcome to the Arduino Based Project which consists of 1602 LCD and Tilt switch module. The basic working of Tilt switch module is being described here. A Tilt Sensor switchis an electronic device that detects the orientation of an object and gives its output High or Low accordingly. Basically, it has a mercury ball inside it which moves and makes the circuit. So tilt sensor can turn on or off the circuit based on the orientation.

CASE 1: NOT TILTED

Initially, when it is in NOT tilted position as shown in the image below, it gives LOW output because of the liquid mercury complete the circuit by connecting the two electrodes. When the output is LOW on-board LED remain ON.

CASE 2: TILTED

When it is inclined in a particular direction or angle, the liquid mercury breaks the contact between the metal electrodes and the circuit gets open. Hence, we get HIGH output in this condition and the on board LED turns off.
