Inclinometers, also known as tilt sensors or tiltmeters, are sensors that measure the inclination or tilt angle of an object relative to gravity. They can be installed vertically or horizontally to monitor the tilt, deformation, or levelness of structures. Inclinometers are widely used in bridge construction, railway laying, civil engineering, building safety, and other applications. There are various types of inclinometers based on different working principles and structures, including bubble-type inclinometers based on mechanical principles and accelerometer-based inclinometers based on electronic principles
