this design is one kind controls the automatic ventilator system warm, is to let the ventilator This ordinary electric appliance even more intellectualization, it has the keen temperature examination and the demonstration function, is takes a control core by the STC89C52RC monolithic integrated circuit, carries on the data acquisition through temperature sensor DS18B20 to the ambient temperature, thus establishes a control system, causes ventilator's rotational speed along with the exterior temperature change, but the automatic control rotational speed, realizes “the temperature to be high, the wind power is big, the temperature is low, the wind speed is weak” characteristic.

The design of Temperature Monitor system can make fan, air conditions or other electrical appliances to become more efficiency and intelligent. In order to establish a temperature controlled system, the monitor was mainly controlled by STC89C52RC single chip microcontroller. With high sensitive monitor technology, the temperature can be analyzed and measured by sensor DS18B20. Base on this technology, the power of fan’s rotated speed will depend on the temperature. With higher temperature, the speed of wind is faster. With lower temperature, the speed of wind is slower.
Key world: single chip microcontroller, sensor, fan

[Abstract] This design is the fan system of an automatic temperature control,it is to make the ordinay fans become more intelligent, it has a sensitive temperature detection and display functions, as a control is STC89C52RC microcontroller core, through the temperature sensor DS18B20 data collection on the ambient temperature in order to establish a control system that allows the fan speed changes with the external temperature automatically adjust the speed, to achieve "high temperature, wind, low temperature, wind speed and weak ".
