Automatic Control Device Design for Kiwifruit Drip Irrigation System Based on STC89C52 Microcontroller

The kiwifruit is very sensitive to water requirements during growth and common drip irrigation systems are overly dependent on human resources．An automatic control device based on STC89C52 microcontroller, that could be used in a fixed drip irrigation system for kiwifruit, was designed．By collecting soil moisture and environmental parameters through sensors, microcontroller made corresponding decisions to control water pump, enabling drip irrigation system to achieve precise and efficient operation, saving labor costs and increasing production．This has certain promotion value and application prospects．
