Dear Michael
The sensor measures rel. humidity directly, see the we page of Bosch: https://www.bosch-sensortec.com/products/environmental-sensors/gas-sensors/bme680/

I need relative humidity, not humidity. Relative humidity is an equation of dew point and humidity. I need relative humidity. Can you add coding for that?

This sensor is 3.3v and not 5v.

And to help anyone reading this, just use a D1 Mini and ESPHome Bsec and have it working fast and easy

My experience is that if you use the BME680 under i2c.
That then the CS and the SDO pins must be connected to the GND.
Then scan for the i2c address with the i2c scanner from Arduino ide.
The module then continues to work stably.
If the pins stay open, they float and sometimes the i2c address changes so that the module is no longer seen by the software.

Thank you for the Guide. My first steps after 30 years without programming ans code. But the problem is the difference between the temperature of the BME680 and other thermometer. I like to try the offset method.
Best regards
Tobias

Hi.
To do that, you need the Bosch BSCE library: https://github.com/BoschSensortec/BSEC-Arduino-library
However, I couldn’t get it working.

Hi,
I wanted to use this sensor as CO2-Sensor.
What means Gas: 66.06 KOhm based on CO2?

In reply to Hamish Low. Thanks, Hamish! I have not used BME680 yet but hope to very soon. Your comments are very helpful. I did not know about the temperature offset or the difficulty with fitting the library into UNO's memory!
