"Inflatable Air Blower" designed to MCU51 microcontroller core, the ambient temperature by a temperature sensor data collection in order to establish a control system that allows fans with temperature changes automatically change gear, to achieve "high temperature, wind, temperature low, weak wind "performance. In addition, through the keyboard control panel, users can set the "Inflatable Air Blower" minimum operating temperature within a certain range, when the temperature is much lower than the set temperature, the fan will automatically turn off when the temperature is higher than the "Inflatable Air Blower" turn restarted, the user can set the minimum working temperature fans, when below this temperature, the fan is automatically stopped.
