A wireless sensor network is used as a distributed system for measuring plant water content in crop fields. The WSN works as a radiometric sensor which gets the information about vegetation water content from the RF communication signals. No specific sensor is needed. The equations of the measurement process are developed based on the two ray propagation model. Experimental results obtained in ...
