Worked on the hoodong/2025-2-Sensor repository to deliver two documentation-driven features focused on sensor technology. Enhanced Markdown-based documentation by clarifying the Tunnel Magnetoresistance (TMR) effect, detailing device structure, and explaining how magnetization impacts tunneling resistance, supplemented with a YouTube reference for deeper understanding. Updated the SL1 Series thermocouple documentation to include a comprehensive breakdown of components, functions, and product specifications, along with an illustrative image. Emphasized clear technical writing and effective knowledge transfer, supporting onboarding and internal collaboration. Demonstrated proficiency in Markdown and documentation best practices, with a focus on accuracy and domain knowledge in sensor applications.
