I dedicate this project to all those that helped me toward this success, specially my parents, my families, my teachers and my colleagues. And do not forget also those who departed from our world of teachers. Thank you all… II ACKNOWLEDGEMENTS I would like to express my gratitude and appreciation to all those who gave me the possibility to complete this project. A special thanks to my supervisor Prof. Sharief Fadul Babikir, who helped me, stimulating suggestions and encouragement, help gratitude to coordinate my project and writing this Thesis. III ABSTRACT Greenhouse is a kind of place which can change growth environment of plants, create the best conditions for plant growth, and avoid influence on plant growth due to outside changing. In this thesis, Android and Arduino based system applied to monitor and control greenhouse irrigation, temperature and humidity designed. The main objective of thesis to afford a cheap technology to control agriculture process. The methodology followed for show the results and control the system by using low power consumption Arduino kit and Bluetooth module. The result obtained show that the system performance is quite reliable and has successfully overcome quite a few shortcomings of the existing systems by reducing the power consumption, maintenance and complexity, at the same time providing a flexible and reliable form of maintaining the environment.
