基于单片机的智能温控风扇系统设计

本文以STC89C52单片机作为主控制器,应用温度传感器、红外传感器、LCD1602显示模块等,对常用的电风扇加以改进,设计了一种智能温控风扇系统。实现当用户在风扇前一定距离、且温度达到预设值时自动启动,在用户离开时自动关闭;随着环境温度的变化自动调节转速;对风扇运行的当前温度和预设的上下限温度进行实时显示等功能,具有一定的实际应用价值与可观的市场前景。

This paper uses STC89C52single-chip microcomputer as the main controller,applies temperature sensor,infrared sensor,LCD 1602 display module,etc.,improves the commonly used electric fan,and designs the intelligent temperature control fan system.It is automatically started when the user is at a certain distance in front of the fan and the temperature reaches the preset value,turned off when the user leaves,adjusted the speed as the ambient temperature changes,displayed the relevant operating parameters of the fan in real time,which has a certain practical value and considerable market prospects.
