Developing a Wearable Air Quality Sensor Package
My most recent profect involved designing and building a wearable air quality sensor package to elucidate spatiotemporal data on air pollution concentration where it is harmful to society. The sensor package is built on the Arduino platform and tracks particulate matter and ground level ozone concentration as well as GPS location and temperature and humidity levels. The project has been featured on local news stations (link) as well as multiple news articles(link1 link2). The team attended the EPA's National Sustainable Design Expo in April of 2016 and will attend the Systems and Information Engineering Design Symposium (SIEDS) at the University of Virginia and the Environment Virginia Symposium at the Virginia Military Institute in April of 2017.
Latest Projects
Natural Gas Meters
As an intern at the Gerdau Steel Mill in Petersburg, VA, my main focus was a self lead project aimed at confirming accurate readings by six natural gas meters used in the Meltshop as well as setting up a data feedback for better tracking of the $500,000 worth of natural gas used each month. Using the product manual, I had to manually verify the calibration of each meter and learn to interpret design schematics to troubleshoot the testing software to obtain accurate readings.
PROJECTS
Below are descriptions of some of the projects I have worked on through out my career as an engineering student.
IR Camera and Ladle Car HMIs
While interning I also assisted the Meltshop Electrical Engineer with projects by developing the HMIs used for the newly installed infrared cameras used for monitoring the electric arc furnace transformer and for the hydraulic load cells installed on a ladle car for measuring the weight of molten steel. HMI development included complying to preset visual design styles, correct data point connections, and animations and alarms to indicate changes in the system.
