In this system, the process is initiated by collecting data of the growing environment measured by sensors and transmitted as inputs to the Arduino processing unit. The controlling system works by processing these data to adjust climate conditions inside the greenhouse. Values of soil moisture, soil temperature, inside air temperature, inside air humidity, inside visible light intensity, ultra violet (UV) light intensity, outside humidity, outside temperature, and outside visible light intensity are measured by sensors of the system. Among these parameters the system is capable to control temperature, humidity and soil moisture levels as per the requirement. A database developed for climatic and soil parameters, both inside and outside the greenhouse, can be used for further analysis. The communication between the Arduino processing unit and computer is achieved via PLX-DAQ software, which also facilitates visualising data using MS Excel and Liquid Crystal Display (LCD). This automated greenhouse is the best solution for the people who are interested in cultivating at domestic or greenhouse levels. Furthermore, this system can be used for research purposes where growth of particular plant is monitored under control climate conditions.
