A Watering Controller System in Mixed Garden Based on Temperature and Moisture by Case Base Reasoning Technique via Wireless Network

Abstract

The purpose of research is to construct paper watering controller system in mixed garden based on temperature and moisture by Case Base Reasoning (CBR) technique via wireless network. The hardware design is an embedded system under Arduino Uno R3 microcontroller which interfaces with sensor and transducer. This microcontroller is able to control temperature and supply the water to vegetable if all information from sensor and transducer are corresponding to the type of vegetable and other parameters in CBR system. The theory of CBR is capable of classifying all data and sequence of all data such as type of vegetable, the appropriate temperature and soil moisture in order to control the watering system. Our system has also communication between all sensor nodes and server computer via Xbee wireless modules which may reduce wire installation. As the experiments, we tested our watering system with Chinese morning glory thereby comparing with the watering systems by using the timer and worker respectively. The results show that CBR method can enhance the growth of Chinese morning glory more than those of other methods. We observe thataverage height of Chinese morning glory in CBR method is greater than the watering systems by using the timer and worker approximately 16.51 percents and 20.82 percents respectively. This CBR method may also support all gardeners due to their fl exibility and convenience to various mixed vegetable gardeners.
