How does the Inclinometer Sensor Work?

[christina]

The inclinometer sensor www.ericcointernational.com/tilt-sensor is actually an application of the MEMS accelerometer, which is the principle that the accelerometer can be used to measure the angular velocity of an object in a static state.

The inclinometer sensor’s theory is based on Newton’s second law: according to the basic principles of physics, inside a system, velocity cannot be measured, but acceleration can be measured. If the initial speed is known, the line speed can be calculated by integrating, and then the linear displacement can be calculated, so it is actually an acceleration sensor using the principle of inertia. When the inclinometer sensor is at rest, that is, there is no acceleration in the side and vertical directions, then the only force acting on it is the acceleration of gravity. The angle between the vertical axis of gravity and the sensitive axis of the acceleration sensor is the angle of inclination. The inclinometer sensor in the general sense is static measurement or quasi-static measurement, once there is external acceleration, then the acceleration measured by the acceleration chip contains the external acceleration, so the calculated angle is not accurate, therefore, the common practice is to increase the mems gyro chip, and adopt the preferred Kalman filter algorithm. The ER-TS-3260VO‘s  www.ericcointernational.com/tilt-sensor/tilt-sensor-preciison-0-3/dual-axis-tilt-sensor.html built-in (MEMS) solid pendulum can measure changes in the static gravity field, convert them into changes in inclination, and output them through voltage (0~10V, 0~5V optional), so that the calculated angle is quite accurate.
