A motion sensor includes a substrate at least having one micromechanical acceleration sensor and a magnetoresistive circuit. The micromechanical acceleration sensor and the magnetoresistive circuit are constructed on the same substrate.

Motion sensor having micromechanical sensor and magnetoresistive circuit on same substrate

An analyzer unit for the measuring signal of a micromechanical sensor having an input/output characteristic which is represented as a characteristic curve includes means for analog-digital conversion of the measuring signal and transmission means for transmission of the converted measuring signal or a signal that depends on the converted measuring signal. The transmission means is designed so that the characteristic curve has at least two ranges having different slopes. Different resolutions of the measuring signal are implemented through the different slopes of the characteristic curve. A suitably resolved signal is thus made available for applications having different sensitivity requirements.
