Traditional "220V Cooling Fan" most prominent drawback is that it can not be adjusted according to changes in temperature timely wind speed, when the early morning when the cooling fan is still at work, but people can not perceive because sleeping is a waste of power resources and easy to cause a cold, traditional mechanical timers limited time range and flexibility unable to temperature changes. In view of the above considerations aspects, we need to design an intelligent "220V Cooling Fan" control systems to solve these problems. 1.DS18B20 digital thermometer for temperature test 2.LCD displays the current temperature, and the display set temperature 3. Fan Smart: When the temperature is greater than the fan rotation set value, when below the set value, fans stop according to current temperature "220V Cooling Fan" automatically selects strong, medium and weak three wind speed 5. Infrared remote control instructions received first remote control using the steps:. A fan switch is turned on smart B.
