I am currently using the BME688 in an office environment. I am leveraging the Sensor API (NOT using BESC or AI-Studio) and am calling bme68x_get_data in Forced mode.
When I first initialized the sensor, I was reading ~12k Ohms for gas resistance. Then, I exposed a random cleaning chemical to the sensor and it brought the resistance down to ~5k Ohms. After that, I blew clean air on the sensor, which increased the resistance to ~30K Ohms. The next day, powering on the sensor, I got up to 600k Ohms.
I would like to know what are the thresholds for gas resistance readings/outputs and whether what I'm seeing is valid. I was unable to find information regarding this in the datasheet.
My question is: What are the min/max values the sensor can output for gas resistance and what threshold indicates a "good" or "bad" environment?
