Inclination sensor principle

Inclination sensor principle

An inclination sensor can be used to measure the change in inclination relative to the horizontal plane. The theory is based on Newton’s second Law, a basic principle of physics that says inside a system, velocity cannot be measured, but acceleration can be measured. If the initial velocity is known, the linear velocity can be calculated by integrating, and the linear displacement can then be calculated. So it’s actually an acceleration sensor that uses the principle of inertia.
When the inclination 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.

With the development of MEMS technology, inertial sensor has become one of the most successful and widely used MEMS devices in the past few years, and microaccelerometer is an outstanding representative of inertial sensor devices. As the most mature inertial sensor application, today’s MEMS accelerometers have a very high degree of integration, that is, the sensing system and the interface line are integrated on a chip.
The inclination sensor integrates the MCU, MEMS accelerometer, analog-to-digital conversion circuit, and communication unit on a very small circuit board. Can directly output the Angle and other tilt data, so that people more convenient to use it.

The characteristic is that silicon micromechanical sensor (MEMS) measures the biaxial inclination change with the horizontal plane as the parameter. The output Angle is referenced by the level plane, and the datum plane can be recalibrated. Data output, interface forms including RS232, RS485 and customizable and other ways. Strong ability to resist external electromagnetic interference.
