Hi there. I have just started to use the BME680 and I want to calibrate the humidity readings as well as VOC readings.
1. Does the BME680 have humidity compensation for the measurement of VOCs?
2. I want to calibrate the sensor but I am not sure how to do that. Would I have to modify the BSEC library to put in a calibration curve for humidity and/or VOC levels? Or is there a code I can use to set calibration parameters? I think there was an Arduino sketch mentioned for setting calibration parameters but I cannot find it in the BSEC zip file that I can download from the Bosch website.

1. It has humidity compensation inside the API and you can find the latest API version for BME680 from GitHub https://github.com/BoschSensortec/BME680_driver;
2. For external calibration, you can find reference device with high accuracy and compensate offset from AP inside the device.
