Second Hospital of Qinzhou,Qinzhou 535000,China) Abstract:Humanbody temperature measurement is the primary means to prevent and control the flu, however, the traditional thermometer has many discommodiousness in application. Based on DS18B20 digital temperature sensor, utilize STC89C516RD+ design multi-drop body temperature measurement system for schools. The system can server for 64 users every minute and show the temperature data by LCD 12864, convenient for the healthcare professionals. Result shows that system has the advantages of low cost, high efficient, easier to manage and meet the requirements measure mass users body temperature quickly.
