Water temperature control system are introduced in this paper, the basic principle of this system can be used for water dispensers circuit, such as the core of the whole system is AT89C51 single chip microcomputer, it is the main control unit to the system, the water temperature control temperature control system is also indispensable, of course, the application system, the temperature control system of temperature sensor DS18B20, after collecting temperature using digital tube display the current temperature, and through the relay on the heating, etc. Overall water temperature control system in the life of a large number of applications for our brought convenient, improve the quality of our life. Keywords: water temperature control system of single chip microcomputer AT89C51 DS18B20 relay .  目 录 前言 1 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc2936 1 水温控制器背景 PAGEREF _Toc2936 1 HYPERLINK \l _Toc29555 2 方案比较 PAGEREF _Toc29555 1 HYPERLINK \l _Toc22011 2.1 控制电路的方案比较 PAGEREF _Toc22011 1 HYPERLINK \l _Toc32170 2.2 温度采集模块 PAGEREF _Toc32170 2 HYPERLINK \l _Toc31924 2.3 显示模块 PAGEREF _Toc31924 2 HYPERLINK \l _Toc12673 2.4 温度控制模块 PAGEREF _Toc12673 2 HYPERLINK \l _Toc205 3 硬
