Infrared heat release probe automatic controller circuit diagram
The controller is used for the fan as automatic controlling. The role is to make the air flow, then the body's sweat is evaporate quickly and absorbs body heat to make people feel cool. In fact, people's feeling is not only determined by the temperature, when air is relative humidity, although temperature is not too high, people will still feel hot, so the relative humidity can not be ignored. In addition, the controller shown as the chart considers the temperature, but also it takes into account the relative humidity. When the relative humidity is below 70%, the temperature is above 30 ℃ and in the control range, the fan will start automatically.   (View)
