S- oil testing and display of temperature and humidity system takes Temperature and humidity sen- sor SHT - 11 as inductive components, it will detect the soil temperature and humidity value and input the value to the AT89C51 microcontroller,then the temperature and humidity value will be output to LCD screen displayed. Automatic watering system design for intelligence and manual two parts.Intelligent watering part through the microcontroller program setting the upper and lower water attained,then comparing this upper and lower water attained with the vale that throug -hing SHT-11 inputting to the microcontroller. When below the limit SCM outputs a signal to o- pening the Electromagnetic valve ,and Start watering .if Above the upper limit value,the SCM will output another signal to Turnning off the Electromagnetic valve ,and Stop watering. Manual part read the time from the clock chip DS1302 by m
