Abstract
A sensor apparatus includes: a sensor that includes a resistor bridge circuit; a temperature detection circuit that provides a first path and a second path; a voltage measurement portion that measures a voltage of each of the differential output terminals; a controller that causes the voltage measurement portion to measure the voltage of each of the two differential output terminals; and a calculator that calculates a difference between the voltages of the two differential output terminals to acquire temperature information of the sensor.
