The electrical water heater is a kind of home appliances that bathroom, loo and kitchen can use, with raising of quality of human live, the modernistic household electrical water heater has abandonned the past way, but adopts a kind of implementation scheme of more accurate ,safety. C language possess many merits for programming of singlechip, such as:Is easy to ransplant, having little bug when sentence construction review, fastness good, the head document type is so many that expediently quickly using various function etc. The writer adopts an AT 89 Cs 52 singlechip to be the controller and using C languages to write programming ,design a style of intelligence household electrical water heater.Use array form keyboard input temperature, the temperature can be accuratly recognized to 0.1 ℃, and use LED light display it, can accurately provide to the warm water of temperature that user needs.Adopt DS18 B20 to collect temperature, use LED
