The senior design team working at the laboratory presented their final working product at Engineering-Days at the Lory Student Center. The senior design team had worked hard over the past two semesters to build a low-cost, low-power and autonomous air quality monitor that could measure, in real-time, ambient concentrations of carbon dioxide and three other pollutants regulated by the Environmental Protection Agency (carbon monoxide, oxides of nitrogen and ozone). Their efforts paid off and E-Days was a grand success. Congratulations!
