Any recommendation for CO2 sensors?
- ondori 4y agoscd30 does the trick
- moloch-hai 4y agoThe main thing you need to know about a CO2 sensor is that you also need a pressure sensor for its readings to mean anything. Expect to pay ~$50 for an actual CO2 sensor. The cheap "organic gas" VOC sensors don't qualify. But you probably should add on one of those anyway.

- MertsA 4y agoThe grandparent ships out the SenseAir S8 for CO2 so presumably they're still happy with it. I have no complaints myself but I haven't compared it to any reference standard. He's the founder behind AirGradient. https://www.airgradient.com/open-airgradient/ https://www.airgradient.com/open-airgradient/ They have a DIY version that's an open source design and you can either source components yourself or just skip trying to track down everything on the BOM and buy a kit from them that comes with a sleek injection molded housing as well.
