Abstract
PURPOSE: To enable setting of temperature at hand, to transmit the measured temperature and to facilitate the control of the temperature in a room by sending a set temperature information from the side of a transmitter.
CONSTITUTION: A frequency corresponding to the resonant frequency of the elastic surface-wave element whose resonant frequency changes corresponding to the temperature of a constitution substrate is outputted by an oscillator 8. On said occasion, the power source of the oscillator 8 is put on and off in accordance with the output of a circuit 27 which outputs a set temperature according to a signal designated by a temperature setting switch 22. Therefore, an electric wave having the prescribed intermittence and the pertinent temperature information is transmitted from an antenna 12. Meanwhile, on the receiving side, the transmitted frequency is detected 28 from the output of an antenna 24 and a temperature setting signal set by the switch 22 is detected 29.
