Abstract
 Along with electronic technology swift development, people's life obtained the radical change. Microcomputer's appearance enables the modern science research to obtain the qualitative leap, but monolithic integrated circuit's appearance has brought enormous convenient for the modern industry control as well as the daily life, was precisely the electronic technology development enhanced the industrial production as well as people's living standard. In energy day by day anxious today, electric boiler, water dispenser, electric cooking pot and so on domestic electric appliances when heat preservation, because its simple controls the system warm, the application is extremely widespread.
 What this topic research is "based on Monolithic integrated circuit's Water dispenser Temperature control system Design". Using the 89C51 monolithic integrated circuit is the core, the coordination temperature sensor, the signal processing electric circuit, the display circuit, compositions and so on output control electric circuit, the software selects the assembly language programming. The monolithic integrated circuit may the water temperature simulation quantity which examines the temperature sensor transform the digital quantity, demonstrates on the LED monitor. This system flexible, the simplify operation, the reliability to be high, will have the broader development prospect.
