Accurate temperature and humidity display

Ultra low power battery powered standalone meter which displays accurate and precise humidity and temperature on segmented LCD. For first version I am using custom LCD design found on Aliexpress which fits perfectly to display both. I went with rechargeable button cell LiR2450. To store the measurements there is on board low power 64KB EEPROM. For initial run I included several relevant sensors for evalution, including for pressure. Later I will downselect most accurate parts as well as the lowest power consupmtion ones. When submitting the project to JLCPCB assembly I found additional fee for BGA X-Ray scan, so I will do without the HDC2010. Software is to be written after I get the prototype boards.
