Research and Exploitation of Precise Irrigation-Fertilization Controller

Develops a general structure of a Precise Irrigation-Fertilization Machine. Introduces the designing ideas of the hardware and software structure of Precise Irrigation-Fertilization Controller, which is the hard core of the machine. MSP430F149 is used as the manager and controller of sub-modules of the precise irrigation-fertilization controller, such as time module, memory module, valve control module, EC/PH measurement module and estate detection module, power module and so on. The paper particularly introduces the schematic diagrams and flow charts of the controller and its main sub-modules. The simulation result shows that the controller designed in the paper can realize the intended function accurately, and come up to the design requirement as well.
