This paper describes the design and implementation of a wireless sensor network for greenhouse environment monitoring. The sensor network was deployed in a commercial aeroponic greenhouse that produces lettuces in a tropical environment. The sensor node was developed using off-the-shelf components and consists of sensors, a micro-controller and a low-powered radio module. Real-time data enabled the operators to characterise the operating parameters of the greenhouse and also to respond immediately to any changes in the controlled parameters. The sensor network achieved data transmission rates of more than 70%.
