Advantages of wireless sensor networks in greenhouse environment

This paper describes the implementation and configuration of the wireless sensor network using the Sun SPOT platform. Sun SPOT is a small electronic device made by Sun Microsystems. They have a wide variety of sensors attached to it. Sun SPOTs are programmed in a Java programming language, with the Java VM run on the hardware itself. It has a quite powerful main processor running the Java VM ldquoSquawkrdquo and which serves as an IEEE 802.15.4 wireless network node. The SPOT has flexible power management and can draw from rechargeable battery, USB host or be externally powered. The Sun SPOT is designed to be a flexible development platform, capable of hosting widely differing application modules. As it is well known, greenhouses have a very extensive surface where the climate conditions can vary at the different points. In the last years, WSNs are becoming an important solution to this problem.
