Worked on enhancing power monitoring reliability in the espressif/esp-iot-solution repository by addressing a critical bug affecting current measurement accuracy. Focused on embedded systems and hardware integration, the developer corrected the interpretation of the INA236 sensor’s voltage shunt sign bit using C, enabling accurate detection and reporting of negative current values. This fix improved data integrity across the entire current range, supporting more reliable energy analytics and better power management decisions. The work demonstrated proficiency in low-level register handling, sensor driver development, and git-based code quality practices, contributing to a more robust and trustworthy power monitoring pipeline.
