Described herein are various embodiments of an apparatus, system, and method for controlling the irrigation of an area. In one embodiment, an apparatus includes at least one sensor module that is configured to detect the soil moisture content of soil in an irrigation area. The sensor module is further configured to determine a rate of change of the soil moisture content based on the detected soil moisture content. A rate at which the sensor module detects the soil moisture content of the soil is based on the determined rate of change of the soil moisture content. The apparatus also includes a central control module that is configured to execute an irrigation event for an irrigation area if the detected soil moisture content reaches a moisture content lower threshold. The central control module also is configured to terminate the irrigation event for the irrigation area if the detected soil moisture content reaches a moisture content upper threshold.
