Water-saving irrigation in this paper, the research on the issue of single-chip puter control system, the system could be used for different soil humidity testing, and timely in accordance with the requirements of the crops on soil moisture, adequate water. This work is based on STC12C5A60S2 micro - controller design bottom hardware system mainly consists of soil moisture sensor,signal transfer circuit , monitor display circuit ,our port control circ uit , malfunction display cir c uit and the procedure programmed with C assemble language. Single chip puter can change the humidity of the soil moisture sensor to convert the amount of soil moisture toa digital quantity, and displayed on the LCD display. According to set value judgment, if need to infuse water, then single chip puter system start singing sound alarm, signal to infuse water, open water ic valve. The high design flexibility, easy operation, high reliability, has the characteristics of convenient, quick and economic, to irrigation in time according to the soil moisture .
