ABSTRACT:
An irrigation system (10) includes one or more alignment guides (38) and an irrigation unit (20). The irrigation unit (20) directs irrigation fluid (19) to at least a portion of an irrigation region (30). The irrigation unit (20) includes a nozzle (220), a sensor (260) that senses a change in position of a portion of the irrigation unit (20) relative to the alignment guides (38), and a unit control system (240). The sensor (260) can be an infrared sensor. The unit control system (240) receives information from the sensor (260) regarding the change in position and adjusts a flow rate of irrigation fluid (19) through the nozzle (220) and/or a position of the nozzle (220) relative to the alignment guides (38). The alignment guides (38) can be formed from a heat absorbing material that is sensed by the sensor (260).
