Sensor module that switches plural sensors capable of measuring different ranges to extend dynamic range

摘要

An output of a first sensor having a low sensitivity and an output of the second sensor having a high sensitivity are compared with each other, and thus it is determined whether a physical quantity becomes larger than a maximum value of a physical quantity capable of being measured in the second sensor. A sensor module is provided which is configured to switch a plurality of sensors capable of measuring different ranges and to extend a dynamic range by selecting the output of the second sensor in a selection unit in a case where the output of the first sensor and the output of the second sensor are coincident with each other, and selecting the output of the first sensor in the selection unit in a case where the output of the first sensor and the output of the second sensor are not coincident with each other.
