A wireless sensor network (WSN) is a system consisting of a collection of nodes and a base station. A node is composed by a processor, local memory, sensors, radio and battery and a base station is responsible for receiving and processing data collected by the nodes. They perform collaborative activities due to limited resources, such as battery, processor and memory. Nowadays, the applications of WSNs are many and varied, and the applications in agriculture are still incipient. One interesting WSN application is in greenhouses, where the crop conditions such as climate and soil do not depend on natural agents. To control and monitor the environmental factors, sensors and actuators are essential. Under these circumstances, WSN should be used to make a distributed measure, spreading sensors all over the greenhouse. In a great number of applications the sensors are located in a fixed point of the greenhouse. However, even in a greenhouse there are differences between some environmental variables from one place to another. Thus, using WSN should guarantee not only real time monitoring, but also guarantee a better control. This paper presents a proposal of greenhouse control using WSN, its advantages, challenges and future applications.(Download PDF) (Export to EndNotes)
