Using enviro:bit for Air Quality Station

Hi all,

I have a question regarding the enviro:bit for micro:bit.

I read on the website and on the packaging that you can use the enviro:bit to make the Air Quality station. I was curious if anyone had tried it. I mean, how do you make one since there is no eCO2 sensor on it?

Does anyone know how to do this using temperature, humidity, and pressure?

Thanks in advance,
