We started out our day at UNT's EESAT facility where each team presented their first steps in addressing each of their project problems. Our Aquaponic team will design a 3 tier aquaponic system with an integrated sensor cluster to monitor pH, temperature, dissolved oxygen, and the water level of our tank (see below). The ultimate goal is to remotely access live stream data for tank conditions and to create a control system to maintain aquarium conditions. This includes, maintaining constant water level through a water-level triggered circuit to open/close the water inlet; maintain temperature through a heater system, based upon temperature readings; a timer-controlled motor to drop fish food; pH will be maintained using a second dispensing system.
We will once again use the arduino microprossesor, Xbee, and atlas sensors to monitor tank conditions. We are fortunate enough to have with us Vardhman which has taken the initiative in activating and connecting our sensors. Alhough last years experience with Atlas sensors will create a voltage drop monitoring problem which we will have tackle.
Our project introduction were followed by a facility tour then a short lecture over water conservtion and reservoirs in the trinity river basin.
Dr. Yan Wan gave a seminar over understanding the interdisciplinary asset and fundamental principles of control including “Dynamics” and “Closed-loop”. This seminar was useful since we are expected to create and maintain an autonomous monitoring system for our tank.
