Developed core driver support for environmental sensing within the Northeastern-Electric-Racing/Embedded-Base repository by implementing the HDC2021 environmental sensor driver. This work enabled accurate temperature and humidity readings as well as internal heater control, integrating sensor data pathways directly into the embedded system. Leveraging C programming and embedded systems expertise, the developer focused on reliable data collection and energy management capabilities for performance applications. The approach emphasized maintainable driver development and clear version control practices, including collaborative commit authorship. No bugs were reported or fixed during this period, reflecting a focused delivery of new functionality rather than iterative maintenance or debugging.
