Mercury switch sensor module

Mercury switch sensor module

Features:

Mercury switch sensor module

• When the module tilts, it outputs low and the corresponding LED lights up
• Working voltage: 3.3V~5V

Supplied With Cable 

Note

Mercury is a toxic substance, Please be careful to avoid breaking the case.

This device allows you to configure the component as a switch. It can be used for the purpose of detecting vibration or applied for detecting tilt in a specified mechanical direction.

They are usually made by a cavity of some sort (cylindrical is popular, although not always) and a conductive free mass inside, such as a blob of mercury or rolling ball. One end of the cavity has two conductive elements (poles). When the sensor is oriented so that that end is downwards, the mass rolls onto the poles and shorts them, acting as a switch throw.

How do you test a tilt sensor?

Testing your sensor is simple. Put your multimeter into continuity-test mode and touch the probes to the two leads. Then tilt to determine the angle at which the switch opens and closes. When pointing down, the switch is Open Loop (no continuity).

What is a tilt sensor used for?

Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances.
