Abstract
A sensor circuit includes an analog-to-digital converter, a control circuit, a calculation circuit, and a pulse width modulation converter. The analog-to-digital converter converts an electric signal associated with a detected physical quantity to sensor data by sampling the electric signal a predetermined sampling number times per a predetermined sampling section. The control circuit determines the sampling number based on a magnitude of the electric signal. The calculation circuit calculates an average value of all the sensor data per the sampling section. The pulse width modulation converter generates a pulse width modulation signal having a pulse width corresponding to the average value.
