Traditional "Mini Air Cooling Fan" 220V AC power supply is used, the motor speed is divided into several stalls, adjust the motor speed to change the wind speed by manually aim, that is, every time the wind changed, inevitably someone involved in the operation, so will bring a lot of inconvenience. SCM smart "Mini Air Cooling Fan" governor design that cleverly using infrared remote control technology, microprocessor control technology, variable speed technology and temperature sensing technology, the intelligent control technology to control appliances, The electric "Mini Air Cooling Fan" of the motor speed is controlled as the amount collected by the microcontroller analyzes digital temperature signal, and then through the SCR fan motor speed. So as to achieve without human control will automatically adjust the effect of the wind speed.
