ilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, and can be mounted using mechanical threading, magnets, or adhesives, depending on what type of surface they are being mounted to. Recent technological advancements in the manufacturing of tilt sensors have improved accuracy, reduced cost, and increased lifetime.

The type SW-520D is a commonly available roller-ball type tilt sensor consists of two conductive elements (poles) and a conductive free mass (rolling ball), encapsulated in the same case. When the tilt sensor is oriented so that that end is downwards, the mass rolls onto the poles and shorts them, acting as a switch stroke. Microcontroller-compatible tilt sensor modules based on SW-520D are also available at affordable costs.
