While this is an interesting RasbPi based device (I think it is neat to see new realworld applications of the Pi), for some areas like mine in central Illinois the low sensitivity kind of is a deal breaker. If it were to sound an alarm like a smoke detector (didn’t play the whole video) it would be a bit more interesting. What I am interested is another Davis external box like the external anemometer transmitter that would host a CO2, radiation, air clarity sensor or other, that could be hosted natively by updates to say VWS, WD, Cumulus, etc. I know about some of the weather software having “extra sensors” settings. I am not talking about a self made box for CO2, a box for radiation…etc. but an external box like the Davis anne transmitter where you plug in the additional sensors (hopefully more affordable than the UV) and check a box in WD or VWS or Cumulus to activate and display the data. Davis, OS, Rainwise, etc…ya listening ?
