1. A data communication system including a sensor measuring a given state and a sensor control device capable of communicating with the sensor,the sensor comprising:

  • a measurement unit configured to measure a given state at a predetermined time;

    a predicted-value retention unit configured to retain a predicted value of the given state transmitted from the sensor control device;

    a calculation unit configured to calculate data to be transmitted to the sensor control device based on a measured value obtained by the measurement unit and the predicted value retained by the predicted-value retention unit; and

    a first transmission unit configured to transmit the data obtained by the calculation unit to the sensor control device, andthe sensor control device comprising;

    a measured-value generation unit configured to generate the measured value obtained by the sensor based on the data transmitted from the first transmission unit and the predicted value;

    a storage unit configured to store the measured value generated by the measured-value generation unit;

    a predicted-value generation unit configured to generate a predicted value of a measured value to be measured next based on the measured value; and

    a second transmission unit configured to transmit data of the predicted value generated by the predicted-value generation unit to the sensor.
