The document summarizes the results of an experiment using an automatic hydroponics system with a myDAQ device. The system was tested at three different EC values (0.5, 0.25, and 0.35) by activating different water and fertilizer pumps. The system worked as intended, turning the appropriate pumps on and off to maintain the target EC values. The system demonstrates a new automatic hydroponics innovation using myDAQ that could be effectively utilized for teaching activities.
