基于单片机的智能风扇的设计与实现

为了解决传统风扇无法进行人体感知从而导致损耗大量的电力资源且存在安全隐患,设计开发了一个智能风扇系统。该系统以单片机为核心,采用DS18B20温度传感器采集数据,将周围环境温度在LED数码管上实时显示,根据实时温度与系统设置的阈值,同时人体红外模块监测周围环境是否有人,来决定风扇是否开启,当没有人在房间时,风扇自动关闭。该智能风扇系统不仅克服了传统风扇的缺点,还具有很好的安全性,低功耗,低成本以及自动监测温度等优点,为人们生活带来了便捷。

In order to solve the problem that the traditional fan can not perform human perception, which leads to the loss of a large amount of power resources and has potential safety hazards, an intelligent fan system is designed and developed. The system takes the single-chip microcomputer as the core, uses DS18B20 temperature sensor to collect data, and displays the ambient temperature on the LED digital tube in real time. According to the real-time temperature and the threshold set by the system, the human body infrared module monitors whether there is someone in the surrounding environment to determine whether the fan is turned on. When no one is in the room, the fan automatically turns off. The intelligent fan system not only overcomes the shortcomings of the traditional fan, but also has the advantages of good safety, low power consumption, low cost and automatic temperature monitoring, which brings convenience to people's lives.
