摘要：近年来，人们对生活质量的追求不断提高，住房面积扩大，不论挂机还是分体式柜机，都无法满足为许多房间同时供热供冷的需求，而且近几年的室内空气质量不让人满意。基于上述的局限性，小型家庭空调系统得以诞生。小型家庭空调系统具备调节空气质量，调节室内温度，还能够通风换气、调节湿度、保证室内的空气健康。科学技术正在随着时间推移越发进步，物联网技术逐渐被人提起，并且逐步普及到我们生活的各个领域中，使得未来的智慧地球成为可能。如果能借助现有的已开发的电脑或者手机的Wi-Fi和互联网功能，去控制小型家庭中央空调系统，将大大提高温控器的智能化程度。62178
本文以单片机为家用Wi-Fi温度监测系统的核心，通过Wi-Fi模块和手机代替上位机完成远程监测温度的功能。在一个家庭房屋大小的范围内，自动控制系统的控制下，较准确的监测室内温度。使用单片机STC89C52，温度传感器DS18B20和LCD液晶显示装置以及小型Wi-Fi发送接收装置来实现。整个设计的工作原理是利用单片机DS18B20采集家庭的室内温度，通过串口装置传递到Wi-Fi模块，再利用家用Wi-Fi网络将数据传递给笔记本电脑或手机来监控温度。上位机（本设计采用笔记本电脑和手机）可以利用无线信号和通信的串行端口的优势将目标温度发送到单片机，而单片机内置的PID算法则用于温度控制。

Design for the Intelligent Domestic Thermostat Based on Wi-Fi Communication
Abstract: In recent year, with housing area expanded and requirement for the continuous improvement of the quality of life, hanging and splitting air condition can’t meet the needs of cooling or heating many rooms at the same time. And the indoor air quality is not satisfactory. Based on these limitations, emerge as the times require household central air conditioning system in a small. Small family of central control system should be adjusted with the air quality. It can adjust not only the indoor temperature, but also regulating humidity, ventilation and maintaining indoor air quality. With the continuous progress of science and technology, the Internet of things technology began to spread to all areas of our lives. It is possible for the wisdom of the future of the earth. If the computer or mobile phone with Wi-Fi and internet function can be used to control the small home central air-conditioning system, it will improve intelligent of the thermostat.
This article is a microcontroller as the core of the wireless temperature control system, mainly to complete the remote temperature control function via Wi-Fi module. Within a certain range, under the control of the automatic control system, the temperature is always within the scope of people's claims. It uses microcontroller STC89C52, DS18B20 temperature sensor and LCD devices such implementation. The basic working principle is the use of SCM DS18B20 temperature acquisition, through the serial port is passed to the WIFI module, and then using a radio signal to pass data to the host computer (laptop or phone) for temperature display. At the same time, the PC can take advantage of the wireless signal and communication serial port to send the target temperature to the microcontroller, the microcontroller with built-in PID algorithm for temperature control.
