Just know that VOC sensors are not very reliable in general and eCO2 is completely unreliable. You can't go wrong with NDIR but $60 sounds quite excessive when you can get a senseair S8 for $10-12 on taobao.
- throwaway81523 5y agoThanks, I wasn't familiar with the Senseair S8. I had ordered the Adafruit one after checking Seeedstudio and finding that the ones there were almost as expensive. The Adafruit one is on a breakout board with a JST connector for their Stemma QT system (similar to Grove and Qwiic) so you can plug it into a cpu board without soldering. I see on Aliexpress, there are a bunch of vendors selling the Senseair S8 for around $26, but other vendors are selling as low as $16 and some others over $35. I wonder whether the very low priced ones are fake or anything like that. Oh well, the solderless connector will make experimentation easier. If I build more of these I'll get some of the Senseair modules.
