Soil Moisture Control System for Melon Cultivation in Greenhouse

Abstract

This research presents melon cultivation in greenhouse using environmental control methods such as temperature, air humidity and soil water. The microcontrollers and equipment were applied to support the growing pattern. Growing melon with soil in the greenhouse consisted of three environmental factors: temperature, humidity in the greenhouse and soil moisture. This research employed a method of temperature control inside the greenhouse by cooling off, controlling moisture in the air by spraying water, and controlling the moisture in the soil grown with drip irrigation system. The experimental results of the environment control system for growing melon in the greenhouse found that the proper temperature was in the range of 28–30 °C, the proper humidity in the air was 70–80%, and the soil water retention by maintaining the moisture level was 80–99% (water content relies on the age of the plant). According to the analysis of temperature control, air humidity, and soil watering, the systems is continuously able to work. Moreover, the developed system can control the atmospheric conditions in the greenhouse to be precisely and accurately defined.
