https://www.co2meter.com/collections/sensors has a bunch of different ones, I usually look on Mouser also. I don't have a name of one currently. I've been using the particle.io platform with a particle device/LTE for sending out data and programming them.

None of them are in the 8$ range. There also seem to some copies which are way overpriced.
