<p>PURPOSE:To detect plural areas by a single infrared-ray sensor and to detect whether or not a person is present in respective areas through a human body detecting device by converging infrared rays through a condenser lens and making only a desired area of the infrared rays reach the infrared-ray sensor, and detecting the temperature in a room by the areas by a temperature output device. CONSTITUTION:The temperature detector 17 sends its output signal (a) to a timing switching device 19 at the timing of the output signal and the device 19 receives the timing of the signal (a) with an input signal (b) and drives an infrared-ray scattering device 14 at timing of each of timing signals (c) - (f). Then only the desired area of the infrared rays which are converged through the condenser lens 13 is transmitted by the device 14 to the sensor 13 and the temperature output device 16 detects the temperature of respective areas in the room to detect the areas by the single sensor 13. Further, the functional component is replaced with an electric component to minimize the price of a temperature detection part 9. Further, the human body detecting device 18 is provided to detect whether or not a human body is present in respective areas.</p> |
