Abstract
A sensor control circuit for controlling a sensor unit for measuring a physical value includes a timing controller which selects periodically one or more sensor units among multiple sensor units and converts an output signal from the sensor unit to a continuous serial input signal, an oscillator which receives the serial input signal input by the controller and outputs a frequency signal corresponding to the output signal detected by the sensor unit, a counter which counts for a predetermined duration a number of pulses of the frequency signal output from the oscillator, a data converter which converts the number of pulses to voltage data and outputs the data, and an RLC selector which inputs to the converter information indicating a characteristic value on which the number of pulses is based. The characteristic value is resistance, inductance or electrostatic capacitance. The sensor units measure physical values, respectively.
