Review: Intelligent Irrigation System for melon in green house

The price of melon varies with its quality. It is very difficult to control the quality of melon in various growing stages, because irrigation management in a green house influences the fruit quality. In this study, the intelligent irrigation systems were developed using the know-how extracted from an expert. Fuzzy control and On-off control for irrigation were examined. Changes in soil moisture content were predicted by Fuzzy control systems with various climate sensors. As the results, the performances in Fuzzy control and On-off control were respectively 52% and 40% water saving compared to the manual irrigation by an expert. The qualities of fruits by Fuzzy control and On-off control were almost the same results from the manual irrigation.

Both the Fuzzy control area and On-off control area gave considerable water savings over the Manual-irrigation area, while both produced fruit of similar quality (sugar content and grade) to that in the Manual-irrigation area. The above shows that the present systems for automatic irrigation control of greenhouse melons are effective. Moreover, no clear difference was seen between the Fuzzy control and On-off control areas. In the future, it will be necessary to conduct cultivation experiments under different soil conditions, and then based on the results to improve the system and increase its general applicability

Let’s know the Arduino

Winter @ kashiihama. Firstly i heard about Arduino when I was study in Electrical Engineering, just heard from my friend who takes thesis topic about arduino for home controlling. I have been looking for a while to his device and just thinking that not related to my thesis in that time.

After discuss and listen to research presentation in end year seminar, about system measuring in tractor movement using arduino by Fukushima Sensei from Mie University, our research team consider to adopt this technology for improve field monitoring and actuating system. In other hand, we have to familiar first with this device and how to program it. Actually this is my first time to do research with arduino, that’s why I start  to learn from official site and step by step to know what is arduino. Continue reading

Mind Map Research, Update III

After laboratory seminar, I decide my research to focus on mobile application, in specific android OS, this device will provide control and actuator for green house. This device will connect with internet and work as gateway and local server for control sensor and device actuator ( water pump, servo motor). This is research schema. Continue reading
