Jiwon focused on enhancing the thermistor documentation within the hoodong/2025-2-Sensor repository, consolidating technical details to clarify how temperature variations affect resistance and how sensor signals are converted into temperature readings. Using Markdown and leveraging strong documentation skills, Jiwon improved the 서미스터.md file through multiple commits, refining grammar, style, and technical explanations. These updates addressed onboarding challenges and reduced interpretation errors for engineering and QA teams by providing a more accessible and accurate reference. The work demonstrated depth in both technical understanding and communication, supporting downstream integration and ensuring that sensor data interpretation requirements were clearly documented for future contributors.
