* Add SEN6X * Adds new SENXX class for SEN5X and SEN6X * Adds CO2 sensor calibration class to be shared among othre CO2 sensors * Make existing CO2 sensor draw from CO2Sensor class * Minor coment for CO2 sensor class * Move away from getRTC in SENXX class to keep track of time changes. * Change all sensors to millis for tracking time, instead of using getRTC * Add comments regarding VOC state * Avoid storing non-valid RTC Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Avoid CO2 sensor warm-up time to be below PM measured started Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Fix limits in CO2 sensor calibration Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Add pragma once on headers * Avoid non-working ASC commands Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Fix data poll * Move pm measure started before warmup check * Make cleaning non-blocking * Restore previous state if cleaning fails. Fix data ready condition. * Fix CO2 sensor checks for calibration --------- Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com>
