Tiny Cooling Fan scientific, advanced

Traditional "Tiny Cooling Fan" of 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, every time the wind changed, there must be people involved in the operation, this will inevitably inconvenience. The design of the intelligent 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 speed. So as to achieve without human control will automatically adjust the size of the effect of the wind. The design STC89C51 microcontroller core, the ambient temperature by a temperature sensor for data collection in order to establish a control system that allows fans with changes in temperature and automatically change gears, to achieve "high temperature, wind, low temperatures, wind weak property ". In addition, you can set "Tiny Cooling Fan" of minimum working temperature within a certain range by remote users, when the temperature is below the set temperature, the fan will automatically shut down when the temperature is higher than the fans to start afresh.
