摘 要在日常生活中发现传统风扇的使用有些不方便的地方， 比如在很多的地区昼夜温差大，人们睡觉时一般依靠风扇的定时功能， 这样可能出现风扇因定时到了而关闭， 但温度并没有降低很多， 也有可能温度降低了很多但定时没有到， 风扇还在转动。 为解决这个问题本文简绍了一种智能温控风扇系统，具有温度检测和显示功能，使用 STC89C52单片机作为系统对风扇的转速进行控制。7 X/ l: U% o8 Z+ R: |- U
此风扇设计两个档位， 由单片机根据 DS18B20温度传感器传来的数字信号进行控制，当温度高于上限值时，风扇较快转动；当温度处于上限值与下限之间时，风扇较慢转动；当温度低于下限时，风扇停止转动。

Abstract
1 V( J% B' J# {5 KThere are some inconvenient places in the use of traditional fan in daily life, such as many regions of the temperature difference between day and night, people generally rely on timing function of fan, the fan may be shut down when the timer goes , but temperature did not reduce a lot of, In order to solve this problem, this paper introduces a fan system controlled by temperature , which has the function of temperature detection and display, and control the speed of the fan by using STC89C52 single chip microcomputer as the system.
