System Architecture
- Gas injection via mass flow controllers (H₂, CH₄, C₂H₆)
- Primary mixing chamber followed by a dedicated sensing chamber
- Intrinsically safe valves and pumps
- Low-pressure operation governed by lab-developed SOPs and hydrogen safety training
My Contributions
- Mechanical design of the sensing chamber, iterated through five revisions
- Design of a custom PCB to control a Raspberry Pi and system actuators
- Integration of mechanical, pneumatic, and electrical subsystems
- Preparation of a complete mechanical drawing package (~100 pages)
Iteration and Testing
Design iterations focused on simplifying part count, improving sealing reliability, and reducing operational complexity. Manufacturing-driven changes improved assembly speed and test repeatability while maintaining experimental flexibility.
Data & Transition to Deployable System
The testing rig generated high-quality sensor data across controlled gas mixtures. This data supported downstream analysis and machine-learning efforts that informed the design and behavior of the portable sensing unit developed in Project 4.2.
Project 4.2 — Portable Hydrogen Sensing Unit
Project 4.2 — Portable Hydrogen Sensing UnitDeveloped a portable, battery-powered hydrogen sensing unit informed by laboratory testing results. The system reported hydrogen concentration in real-world conditions and was delivered as a polished prototype for client evaluation.
