Maybe this would be a good blog post, but could you speak to the sensors chosen for AirGradient vs other alternatives?
PMS5003T looks only a few dollar more than PMS5003 and adds temp/humidity
PMS5003ST has both temp/humidity and formaldehyde, but not sure of the relevancy of that
BME680 does temp/humidity/pressure, and TVOC/eCO2 although the last two seem to be wild guesses in my experience
I also saw this article with a list of various PM2.5 sensors, and thought it interesting that the PMS5003 wasn’t even in the list.
The best particulate (PM2.5) sensor for ESPHome (home-assistant-guide.com)
So just generally curious which ones you’ve tested and found lacking in capabilities, or which ones just aren’t worth the price/performance balance.
