Abstract
Monitoring and control of greenhouse environment play an important role in greenhouse production and management. To monitor the greenhouse environment parameters effectively, it is necessary to design a measurement and control system. This paper presents a control design of wireless sensor network system based on radio frequency (RF) transceiver for greenhouse, which consists of some sensor nodes placed in the greenhouse and a master node connected to upper PC in the monitoring center. The sensor nodes collect signals of greenhouse temperature, humidity, light and CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> , control the actuators, and transmit the data through the wireless RF transceiver; the master node receives the data through the RF transceiver and sends the data to the upper PC for real-time monitoring. Result shows that the system is practical and reliable, and has wide application in the future.
