Over a two-month period, contributed to the hoodong/2025-2-Sensor repository by delivering six documentation features focused on sensor technologies. Work centered on expanding and restructuring technical documentation for phototransistors, thermopile sensors, AMR sensors, and broadband pyrometers, emphasizing clarity, maintainability, and practical application. Leveraged Markdown and technical writing skills to standardize formatting, enhance onboarding materials, and improve cross-document references. Updates included detailed operating principles, datasheet analyses, and real-world application examples, supporting both developer onboarding and customer support. No bug fixes were reported, as efforts were dedicated exclusively to documentation quality and knowledge transfer within the team’s sensor portfolio.
