Usual co2 detector alternative seem to be sold for around 100$ these days, so that’s nice to see something using recent tech and relatively cheap component! The next step for me would be to add wifi support to feed this data in my domoticz setup!
A sweet project!
Sensors cost $30-ish on aliexpress. Look for ‘scd30’.
Of course, that doesn’t include a microcontroller or i2c-usb adapter to get the data into your computer. But these can be had for ~$2 these days.
I’m at 1000-1500 ppm most of the time, unfortunately. Whenever you see me posting some nonsense, keep that in mind.
