Overview of Smart "Cooling Fan Manufacturer" control system when traditional AC power supply 220v fan motor speed is divided into several stalls, by artificially adjusting the motor speed to achieve the purpose of changing the size of the wind, that is, every time the wind changed, someone is bound to participate operation, this is bound to bring a lot of inconvenience. The design of the Smart "Cooling Fan Manufacturer" control system, refers to the fan motor speed is controlled as the amount collected by the microcontroller analyzes digital temperature signal, and then through the SCR for "Cooling Fan Manufacturer" motor tune speed. So as to achieve without human control will automatically adjust the size of the wind effect.
