Farmland water potential soft-sensing network based on WSN

Abstract

According to the needs of modern agriculture on the crop micro-environment information, the farmland water potential (FWP) soft-sensing network based on WSN could achieve crop micro-environment information collection, processing and transmission. The system was made up of the imbedded gateway and several WSN nodes, and configured relevant WSN nodes based on the requirements of the FWP soft-sensing, such as humiture collection node, illuminance collection node and CO 2 concentration collection node etc. The imbedded gateway received the data of all microenvironment information nodes, estimated the FWP value in real-time and communicated with the remote data center. In practical application, it works well. © 2011 Springer-Verlag.
