uple sensor, PN junction temperature sensor and integrated temperature sensor. Correspondingly, based on the interaction of waves with matter of law, have developed acoustic temperature sensors, infrared sensors and microwave sensors. Temperature sensors are a variety of sensors in a wide variety of the most monly used, modern appearance temperature sensor was very small, so it is more widely used in various fields of production practices, but also for people39。s lives by providing a myriad of convenience and functionality . This article relates to the temperature control system based on singlechip IIImotor speed, the control of single controller, as the temperature sensor DS18B20 temperature acquisition device and pared to control motor speed according to the temperature and the collection system settings, and the system39。s preset temperature is achieved by two independent keys, and a preset temperature increase, a preset temperature is reduced. Key words microcontroller。 DS1820。 temperature control。 第 1 頁(yè) 目錄 第一章 前言 2 第二章 方案設(shè)計(jì) 2 系統(tǒng)整體的選擇 2 單片機(jī)的選擇 2 溫度傳感器的選擇 3 調(diào)速方式 3 第三章 各單元模塊的硬件設(shè)計(jì) 3 DS1820 數(shù)字溫度傳感器 3 AT89C52 單片機(jī) 4 LED 數(shù)碼管 5 第四章 電路的設(shè)計(jì) 6 第五章 軟件的設(shè)計(jì) 8 C 語(yǔ)言程序源代碼 8 用 Keil C51 編寫程序機(jī)器編譯 14 本設(shè)計(jì)基于 Proteus 的仿真 15 第六章 結(jié)束語(yǔ) 1
