| Abstract: | This paper designs an automatic irrigation system based on Panasonic FPI-C40C PLC. The sys- tem relies on the electromagnetic valve and pump motor controlled by the PLC, which compares the soil humidity tested from the humidity sensor with the pre-set ideal figure. In the system, PC is responsible for the centralized management, including regular data acquisition and storage, and timing, quantifying and cycle control of the irrigation. The system is composed of four parts：automatic measuring module, PLC slave computer,PC host computer and irrigation work station. Due to its low cost and easy operation and maintenance,its wide application in the small-scale irrigation of rural areas can be expected. |
