This paper proposes the ‘Paprika greenhouse management system’ based on wireless sensor network technology, which will establish the ubiquitous agricultural environment and improve the productivity of farmers. The proposed ‘Paprika greenhouse management system’ has WSN environmental sensors and CCTVs at inside/outside of paprika greenhouse. These devices collect the growth-environment related information of paprika. The system collects and monitors the environmental information and video information of paprika greenhouse. In addition to the remote-control and monitoring of the greenhouse facilities, this system realizes the most optimum paprika growth environment based on the growth environmental data accumulated for a long time.
