The signal is processed. For example, the detecting unit 37 can determine whether the digital signal is abnormal, that is, whether the digital signal is a correct digital signal indicating a humidity value, and if the digital signal is abnormal, the detecting unit 37 sends a feedback signal to re-receive the digital signal. The signal, if it is judged that the digital signal is correct, records and saves the digital signal and outputs the digital signal to the line transmitting unit.
