And this is exactly why I like to buy AirGradient hardware. Your CO2 sensors are some of the best I've found for the price point, and I love your outdoor monitor as well.

That said; I have started moving towards using SEN5x for a lot of my air monitoring. I've noticed the SHT3x temp sensors pretty consistently flake out after 2-3 years, and the footprint of your current DIY kit is rather larger.

Would you consider an updated version with the SEN6x once it comes out, with perhaps an ESP32c3, rather than the 8266?

Actually since a year or so, we use the ESP32-C3 and the SHT40. You can check our website for the new model [1].
