Abstract
A sensing apparatus includes a microprocessor having an A/D converting function of digital-converting an analog electric quantity supplied to an A/D conversion port and taking in a conversion result, and a plurality of electrical elements that are connected with the microprocessor and generate analog electric quantities. The plurality of electrical elements are respectively connected with a plurality of switch ports in the microprocessor that can be selectively grounded by internal switches of the microprocessor. Analog electric quantities generated in the electrical elements can be selectively taken into the A/D converting function of the microprocessor by selectively switching the internal switches.
