Since a few days I am using a RAK7204 and now I ask myself the question what exactly the values of “gasResistance” mean to me. I didn´t found any information that makes clear statements about what value stands for good, medium or bad air.
BOSCH’s statements on the BME680 environmental sensor indicate that there is an IAQ index that must be calculated. This calculation is usually done directly on the circuit board on which the sensor is used. Since the RAK7204 does not provide an IAQ value, this calculation does not seem to happen.
Therefore my question, can I calculate the IAQ based on the sensor data myself and how, or is there a table for the values of the “gasResistor” from which I can extract the air quality.
Attached is a table I have found about the IAQ values.
Thank you and Best Regards
