Sensor control circuit and sensor

A sensor control circuit for controlling a sensor unit for measuring a physical value, comprising:

• a timing controller configured to select periodically at least one sensor unit among a plurality of sensor units and convert an output signal from the sensor unit to a continuous serial input signal;
• an oscillator configured to receive the continuous serial input signal input by the timing controller and output a frequency signal corresponding to the output signal detected by the sensor unit;
• a counter configured to count for a predetermined duration a number of pulses of the frequency signal which is output from the oscillator;
• a data converter configured to convert the number of pulses to voltage data and output the voltage data;
• and
• an RLC selector configured to input to the data converter an information indicating a characteristic value on which the number of pulses counted by the counter is based,
• wherein the characteristic value is one of resistance, inductance and electrostatic capacitance, the plurality of sensor units are configured to measure a plurality of physical values, respectively, and the timing controller is configured to transmit a signal to connection switches of the sensor units at a predetermined interval such that the at least one sensor unit is selected periodically among the plurality of sensor units.
