基于AT89C51单片机的温度测控系统设计
Design of Temperature Measurement and Control System Based on AT89C51
摘要
Abstract
A temperature measurement and control system based on AT89C51 is designed, whose working principle and design method are introduced. The temperature signal was sampled by digital temperature sensor DS18820, was transmitted to the microcontroller AT89C51 , and was displayed by LED. The 4 X 4 matrix keys were used to set the upper and lower limit of temperature. The control signal would be given by the MCU to start devices when the temperature was out of the range.The experiment shows that the accuracy of the system is 0. 1 ％ , and the available range is-55～＋125 ％. The system can be applied in many fields such as household appliances, cars、warehouse and so on.关键词
