Intelligent Tiny Cooling Fan Control System Overview

Traditional "Tiny Cooling Fan" is 220V AC power supply, the 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, there must be people involved in the operation, this is bound to bring a lot of inconvenience. The design of the intelligent "Tiny Cooling Fan" 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 "Tiny Cooling Fan" motor tune speed. So as to achieve without human control will automatically adjust the size of the effect of the wind.
