have my Enviro+ up and running and set up a custom .py to read values and send them to MQTT. From there on I further use the values in openHAB (Smarthome).
My question is about the Enviro+’ MICS6814 sensor. Right now it reads…
- 566 kOhm redu
- 25k kOhm oxid
- 369 kOhm NH3
Is there a chance to convert these resistances to PPM? I’ve stumbled upon a data-sheet (https://www.mouser.fi/datasheet/2/18/1143_Datasheet-MiCS-6814-rev-8-1144828.pdf) where there are diagrams for RS/R0 over PPM, but the RED sensor diagram only reaches to 10.00 kOhm on Y-axis.
Many thanks in advance!
