    ** WIP **
    The prior senior design team developed an “Electronic Nose” (E-Nose) system capable of detecting minute concentrations of gaseous compounds using a metal-oxide semiconductor (MOS) sensor array. Their system demonstrated early success but the project suffered from limitations in solenoid valve operation, pressure behavior, electronic drift, and prototype reliability. This semester, our team restored the device to a functional state and redesigned the solenoid assembly to be used for multi-chamber testing in the future. Our work also included pressure research using Darcy–Weisbach modeling, experiments to test data-collection and system integrity, and establishing groundwork for multi-chamber support and autonomous test cycles. Future efforts will focus on tuning sensor baselines, introducing sinusoidal heating, improving data-processing, and implementing full automation of sampling and purging cycles.

    Shelby Godbee
    Beginning my academic career as a computer science major, I found that my skills and interests were more aligned with that of electrical engineering. I loved learning about power systems, robotics, and microelectronic systems, and I am looking to pursue a career that involves these areas. I graduate in Fall of 2026.

    Dominic Weiland
    I transferred from Chipola College in Mariana and came to Panama City FSU. My interests are in computers and working around and with them, both with software and hardware.

    Titus Campbell
    I am from Panama City Florida, I am interested in a career in software engineering, and I graduate this Spring.

    Rachel Raffield
    After earning my AA in Music at Gulf Coast State College, I realized that I'd rather perform music as a hobby rather than as a career. I then made the decision to pursue electrical engineering at FSU-PC. The field immediately captured my interest; the endless amount of knowledge to pursue is both fascinating and motivating to me. I am interested in a career in defense, particularly one with a focus on communication systems, radar, and/or electronic warfare and protection. I graduate in Fall 2026.
