High-precision obliquity sensor with combined sensing elements

A high-precision obliquity sensor with combined sensing elements belongs to the field of sensors. The high-precision obliquity sensor with combined sensing elements comprises a tooling module, a sensor shell, sensing element chips, a signal processing circuit module, a power management filter circuit, a microprocessor and a digital output module. More than two small-measuring-range integrated obliquity sensing element chips are fixed, according to positional relation, to the tooling module. When the tooling module rotates with the sensor shell, output signals of the multiple obliquity sensing elements chips enter the microprocessor on the signal processing circuit module successively. The microprocessor acquires corresponding signals of the multiple sensing element chips according to changes of the sensor shell's obliquity relative to the horizontal plane to carry out a programming treatment so as to expand measuring range of the whole obliquity sensor. Through spatial combination of the multiple sensing elem
