Abstract: This design uses the STC89C52 microcontroller and the ADC0832 converter as the core of the system, according to the soil YL-69 soil humidity detected current, compared with the set temperature range suitable for plant growth, if soil moisture value is lower than the set limit value range of SCM, SCM control relay switch is closed, the motor pump to work; if the detection of soil moisture is higher than the value set the upper limit value of “single chip” microcomputer control switch, relay, motor pump stop working. The process of continuous detection and judgment, is the focus of the system function design.
