The AIM system is a feedback control system that continuously monitors agricultural soil conditions through the use of a sensor unit, and a user interface. The sensor unit built using a micro-controller equipped with a capacitive moisture sensor relays soil moisture data to a computer application-based user interface. The interface, designed in Excel for the prototype, reads the soil moisture data and notifies an operator when irrigation of the cropland is required. The interface can then control an irrigation system, supplying water until a desired soil moisture level is detected by the system.
