Abstract

PURPOSE: To display mositure quite obviously and to ensure the adjustment of moisture, by displaying the moisture with illuminating state of light emitting diodes and detecting and adjusting the moisture with the phototransistor.
CONSTITUTION: When the moisture around the moisture sensing resistance element RH2 is 50%, the resistance value is 105 ohms. In this case, in the light emission diode array 5, the input voltage Vin of the IC3 for light emitting diode driving is 3W3.5V and the light emitting diodes LED No.1WNo.6 illuminate. The part of the moisture display plate 8 corresponding to the light emitting diode LED No.6 is taken as the display of 50% and photocurrent flows if the phototransistor 4 is located at this position. The triac 9 in the zero cross circuit 6 is switched by using this current, to start and stop the AC motor and transformer for the humidifier and dehumidifier being the load for moisture control.
