Abstract: Greenhouse technology is the technique of providing favorable environment condition to the plants. It is rather used to protect the plants from the adverse climatic conditions such as wind, cold, precipitation, excessive radiation, extreme temperature, insects and disease. It is also of vital importance to create an ideal micro climate around the plants. It requires intensive sensing of the climate conditions at ground level and rapid communication of data to the central repository. Internet is an emerging field that can be used to monitor and control the agriculture parameters in order to make intelligent automated agriculture system. The system basically comprises of host computer having LabView software and internet connection, ZigBee wireless modules for transmitting and receiving the data signals and PIC microcontroller for calculating the agriculture parameters from the sensor voltage and to control the relays according to the control signals send by the user. PIC microcontroller converts the sensor output into serial data and passes it to the ZigBee module. The ZigBee modules are used to transmit the data from the greenhouse to the host computer. The data from sensing node is amplified and fed to ADC of the PIC microcontroller, this is then connected to the ZigBee module, which transmits the data and at the host end, another ZigBee module reads the data and displays on to the host computer via LabView. By using the LabView web publishing tool this data is published in the internet and secured by using username and password. The website is created by using PHP codes and simulated using WAMP server 2.2.The user can monitor and control the greenhouse parameters by logged into the NITT website with proper username and password. The logged user can view the same LabView window as the host with same functionality. The register facility is also available in the website for the new users.

Keywords: Greenhouse, ZigBee, Internet, LabView, PHP
