简易湿度发讯器和去湿机配用可使室内湿度保持在50～80%之间的任意范围中。此控制仪电路简单可靠,自制方便。每台控制仪材料费仅在50元左右(包括毛发湿度计)。1.结构原理应用光电转换原理,在毛发计上装上两只可滑动的光电器件。当毛发计的指针指到设定的湿度时,遮住光电器件的光源而产生一个信号,然后通过电子线路来控制去湿机工作。电路如图所示。两个光电元件的位置可根据所需要的湿度来调节其上下限。
Simple humidity transmitter and dehumidifier with the indoor humidity can be maintained at 50 to 80% of any range. This controller circuit is simple and reliable, easy to make. Each controller material costs only 50 yuan (including hair hygrometer). 1. The principle of the structure The principle of photoelectric conversion, the device installed on the hair meter can slide two optoelectronic devices. When the hair gauge pointer refers to the set humidity, the light source optoelectronic devices to produce a signal, and then through the electronic circuit to control the dehumidifier work. Circuit as shown. The position of the two optoelectronic components can be adjusted according to the required humidity upper and lower limits.
