This is pretty cool. I’ve been looking to expand / replace PurpleAir with something that monitored gasses in addition to particulate matter. I don’t think this is exactly what I want, since it has an LCD, but the sensors and board are really cool. The only thing I wish this tracked was SO2. I’m thinking i might have to make my own with Arduino. But this is very cool.
