A inclinometer sensor is a device used to measure the tilt angle of an object. The principle is based on the effects of changes in resistance, capacitance, and magnetic induction in physics. Inclinometer sensors are often used for precise measurement of changes in the horizontal angle of objects. They can be used to measure the inclination of the measured plane relative to the horizontal position, as well as the parallelism and perpendicularity of the two components; It has become an indispensable and important measuring instrument in fields such as bridge erection, railway laying, civil engineering, oil drilling, aviation and navigation, industrial automation, intelligent platforms, and mechanical processing.
