This design make the solar water heater add several features such as:water level display,temprature　loading,water　insufficiency　loading,alarm-reporting,high temperature prevention loading and so on. The system is composed of P87LPC764 and HD74HC04P. This article is divided into 3 parts,introduce the use and perspective of solar energy,the form and principle of solar water heater.The circuit schematics and software design are given. Key words :solar water heater;temperature control;sensor; single chip computerPAGE II - - -  PAGE II - 目 录 摘要……  = 1 \* ROMAN I Abstr
