Dr. Esther T. Ososanya is a professor of Electrical and Computer Engineering at the University of the District of Columbia, and the current BSEE program director. During her career, Dr. Ososanya has worked for private industry as a circuit development engineer and as a software engineer, in addition to her academic activities. She received her education in the United Kingdom, where she achieved her Ph.D. in Electrical Engineering from the University of Bradford in 1985, and was a Post Doctoral Research Fellow at the University of Birmingham. She was a Visiting Professor at Michigan Technological University for five years, and an Associate professor at Tennessee Technological University for 7 years prior to arriving at the University of the District of Columbia in the Fall of 2001. Dr. Ososanya's research interests include new applications for VLSI ASIC design, Microcomputer Architecture, Microcontrollers, Nanotechnology, and Renewable Energy Systems. In recent years, she has worked with colleagues to apply these technologies to Biomass research, Solar Cells efficiency capture research, and Renewable Energy Curriculum developments. Dr. Ososanya teaches a myriad of Electrical Engineering courses and labs, including Electric Circuits, Digital Systems courses, VLSI, VHDL, Solar Energy (PV) and Solar Thermal systems, Mechatronics, and Electrical Engineering Senior Project design courses.

Agriculture uses 85% of available freshwater resources worldwide, and this percentage willcontinue to be dominant in water consumption because of population growth and increased fooddemand. There is an urgent need to create strategies based on science and technology forsustainable use of water, including technical, agronomic, managerial, and institutionalimprovements.This paper addresses water scarcity and food crisis by designing and implementing a smartirrigation system. It presents the details of a solar-powered automated irrigation system thatdispenses the exact amount of water required depending on the soil moisture, hence minimizingthe waste of water. A network of sensor nodes is used to collect the humidity and temperature ofthe soil which is transmitted to a remote station. This data will be analyzed and used to remotelycontrol the amout of water dispensed by solenoid valves. The designed project is currentlyoperating at the university-owned agricultural experimental research station. The system can betailored to the type of food or crop being grown. The design team incorporated the theory ofdigital control and feedback system, and digital communication in the design andimplementation of this project.The paper will present the detail of the design, leasons learned from implementing such a systemand suggestions for future improvements.
