  • 1. A HYBRID WIRED/WIRELESS NETWORKING INFRASTRUCTURE FOR GREENHOUSE MANAGEMENT Introduction: In this paper, the problems related to the management of a farm made up of several greenhouses are discussed. The management of this kind of farms requires data acquisition in each greenhouse and their transfer to a control unit which is usually located in a control room, separated from the production area. At present, the data transfer between the greenhouses and the control system is mainly provided by a suitable wired communication system, such as a fieldbus. In such contexts, even though the replacement of the wired system with a fully wireless one can appear very attractive, a fully wireless system can introduce some disadvantages. A solution based on a hybrid wired/wireless network, where Controller Area Network and ZigBee protocols are used, is presented along with all the related problems that this integration involves. A suitable multiprotocol bridge has been implemented. Existing System: In existing method, the data transfer between the greenhouses and the control system is mainly provided by a suitable wired communication system, even though the replacement of the wired system with a fully wireless one can appear very attractive, a fully wireless system can introduce some disadvantages. Hence we propose this system. Proposed System: The system to be controlled is made up of several greenhouses distributed in a field. Each greenhouse is used for the production of several kinds of plants, which can vary according to the season and to the requests from the market. Each greenhouse is equipped with sensor which performs all the activities requested for the correct growth of plants. Sensors are mainly used for the measurement of temperature and humidity, which represent two key parameters inside the greenhouse. In this project consists of two slave node and one master node, the communication

The sensor values are sensed by slave nodes using corresponding sensor, slave nodes are sent sensor information to master node using two wired communication CAN protocol. The master controller sends sensor value to monitoring section using zigbee wireless technology. Using .NET application the sensor data’s are updated with PC. If any abnormality occur means master send control instruction to slave node the control environment condition by switch on the DC motor or exhaust fan to maintain green house environment.
