AbstractIn this paper including temperature and humidity testing temperature sensors humidity sensors microcontroller interfaces and application software design It can be divided into the following parts introduction of temperature and humidity detection technology at home and abroad and analysis of the future of temperature measurement technologies development
The system is based on bined temperature and humidity sensor SHT11 monolithic integrated circuit AT89C51 surveys separately to the temperature humidity and demonstrated through the liquid crystal display monitor 1602 silk thread business This system consists of upper and lower body slave machine plete the acquisition and processing of temperature and humidity then pass them to the 1602 LCD display and judge the ultra limit alarm At the same time puter through RS232 bus is rumored to first degree temperature and humidity machine PC can show the current temperature and humidity values This system has a high readability high stability reaction speed measurement accuracy of characteristics The circuit is simple stable and high integration of the system high accuracy have practical value
Temperature and humidity detection system is base on 8051 bination of temperature and humidity the temperature measurement system The system mathematical model is reasonable easy measurement The actual instruments used anti-interference low zero-drift low temperature drift of ponents perform
