Irrigation system with feedback control from the dimensional distortion of plant organs can realize more precise irrigating,which conforms the requirement of modem fine work.A water-saving irrigation system with a feedback control from the thickness of plant leaf is designed,and the system configuration and its implementation are described in detail.An inductive displacement transducer is used to sense the thickness of plant leaf,which is compensated through the ambient temperature and humidity.The data acquisition card Advantech PCI-1710 links the system hardware and the software of the system upper computer programmed in graphic language LabVIEW,to accomplish the signal transfer and irrigation valve operation in simple and effective way. System testing indicates that the irrigation control system runs in good shape.
