AUA has developed a smart spraying controller
The Smart Farming Technology Group of AUA has created a controller for the OPTIMA Project which is able to control a set of PWM (Pulse Width Modulation) nozzles in order to maximise accuracy and efficiency during spraying. The basis for this functionality is a system from TeeJet Technologies that is modified to be controlled through an external rate controller.
