Hey,
I was recently using some AMS IAQ Core C VOC sensors within an indoor air quality measuring project.
As i switched to the BME680 i have some for sale now.
Maybe this is interesting for somebody as the IAQ Core is quite expensive when bought new:
I´m not sure if it´s allowed to post ebay links here - if not, I´m sorry:

or:
Otherwise just give me a note if you´re interested.
Cheers
