However, increases in measurement points mean increases in installation and maintenance cost. The purpose of this project “AUTO- MATED WIRELESS GREENHOUSE CLIMATE MANAGEMENT SYSTEM” which is capable of intelligently monitoring and controlling the greenhouse climate conditions in a pre programmed manner. The proposed system consists of three stations: Sensor Station, Coordinator Station, and Central Station. To allow for better monitoring of the climate condition in the greenhouse, the sensor station is equipped with several sensor elements such as CO2, Temperature, humidity, light, soil moisture and soil temperature. The communication between the sensor station and the coordinator station is achieved via ZigBee wireless modules and the communication between coordinator station and the central station is achieved via Zigbee wireless modules. The overall system architecture shows advantages in cost, size, power, flexibility and distributed intelli- gent. It is believed that the outcomes of the project will provide the opportunity for further research and devel- opment of a low cost automated wireless greenhouse management system for commercial use.

It plays a crucial role in the continuous development of human civilization. Tradition crop cultivation requires a tremendous amount of hard work and attention and there are several disadvantages in implementing traditional cultivation techniques:  Weather dependent factors: plants‟ growth and development are primarily governed by the weather conditions.  Pests and diseases: plants growing under traditional cultivation technique are significantly affected by pests and diseases. It was discovered that there are indications that already many thousands years ago civilizations in countries such as China, Egypt and India employed means of protection against cold, wind and excessive solar radiation [10]. These methods of protection were employed only to provide a short-term protection for plants against harsh climate conditions. However, no further development occurred until the late 15th century and early 16th centu- ry,when European explorers brought back exotic plants acquired in the course of their travels. Many were tropi- cal plants that could not endure the cold European climates. The result was the creation of greenhouses and the- se early greenhouses were originally referred to as “giardini botanic” also known as “botanical gardens” [11]. A Greenhouse represents a strange kind of agricultural environment characteristics by the presence of several input output devices and control devices. Requirement of human involvement is less compared to open air agri- culture for providing water for irrigation and manures. Greenhouse represents a closed environment which can be strictly controlled by human in order to provide best conditions for the growth of plants. Wireless sensor
