It has a great influence on peoples lives, so the design of the control system of temperature acquisition and research has the very vital significance. In recent years, Electric fans added lots of new features . It doesn’t reveal the individual character, but in virtually it also improves the level. The automatic control of fan’s start and stop can solve the problem which when people are sleeping at night in summer, due to temperature drop and lead to catch cold at night, or waking from sleep to switch electric fan, so it has important practical significance . Therefore, the paper introduces the design of electric fan intelligent governor based on AT89C51 . The design uses AT89C51 controller as the core, skillfully using temperature sensor circuit timely and accurately to collect environment temperature, and using the two-way thyristor to stepless speed regulation of motor. The intelligent control technology is used in home appliances control, and uses the human body environment temperature to realize the control of tempera
