In recent years, "Cooling Fan Manufacturer" added a variety of new features, not only demonstrates the character, but also indirectly raises the level. Fan start-stop automatic control, can be solved when the summer people sleep at night, because the temperature drop caused by the cold at night, or waking up fans personally switch from sleep problems, has important practical significance. Since the purpose of departure, this paper presents a AT89C51 microcontroller-based Intelligent Speed Design "Cooling Fan Manufacturer", which are designed to AT89C51 controller core, the clever use of a temperature sensor circuit, timely and accurate collection of ambient temperature, the use of two-way thyristor for variable speed motors, control technology for the intelligent control of household appliances, with a body temperature of the surrounding environment "Cooling Fan Manufacturer" carried thermostat.
