基于DS18B20的温度控制系统设计

摘要

在工业生产中温度是常用的被控参数，而采用单片机来对这些被控参数进行控制已成为当今的主流。文中介绍了以AT89S52单片机为核心，以数字温度计芯片DS18B20为测温单元的的温度控制系统，该系统通过三极管的通断控制继电器，来控制电热器调节温度，较好实现了温度的智能控制。%Temperature is commonly used parameter to be controlled in industrial production,while the use of single-chip to control those controlled parameters has become today’s mainstream.This paper introduces the AT89S52 microcontroller as the core,chip DS18B20 digital thermometer for temperature measurement unit temperature control system,the system through the transistor on-off control relay to control the electric heater to adjust the temperature to achieve a better control of the temperature of the smart.
