Sensing part 1 is a temperature sensor 11. The output information of the humidity sensor 12 is converted into a temperature signal or humidity signal including pulse numbers corresponding to the temperature and humidity values by the corresponding temperature signal conversion circuit 13 and humidity signal conversion circuit 14, respectively. The converted signals are modulated, for example, by Al, at different frequencies in the radio transmitting circuit 15, and outputted from the built-in antenna.

The temperature pulse detection unit 21 counts the temperature signal including the number of pulses corresponding to the constant temperature measured by the temperature sensor 11 for a certain period of time, for example, one second, and sends the result to the control circuit 23 as temperature data. The control circuit 23 causes the drive circuit 24 to start the heating device 4 when the temperature data rises above a suitable temperature range set externally in advance, and stops the heating device 4 when the temperature data returns to the suitable temperature range. If the constant temperature data falls below the appropriate temperature range, cooling system #5 is activated and stopped when the temperature data returns to the appropriate temperature range. Humidity pulse detection section 2
