Understanding Tilt Sensors
Tilt sensors, also known as inclinometers, are electromechanical devices that measure the angle or inclination of an object relative to gravity. They find widespread use across various industries, from construction and geotechnical monitoring to automotive and consumer electronics. Their ability to detect even slight changes in tilt makes them invaluable for precision applications. The core technology behind these sensors varies, but they commonly utilize MEMS (Microelectromechanical Systems) technology or other sensing principles.
