Developed configurable ADC sensor sampling for the esphome/esphome repository, enabling users to select average, minimum, or maximum sampling modes to improve measurement accuracy and resilience in noisy environments. Enhanced both the C++ core and Python configuration schema to support these new options, ensuring robust integration with existing firmware and hardware workflows. Complemented the technical implementation by updating esphome/esphome-docs, providing clear documentation on the new sampling_mode feature and its usage. Focused on embedded systems and sensor integration, the work improved data quality and reliability across deployments, with careful attention to configuration management and end-to-end clarity for users.
