It'll do battery voltage as it is.

Hopefully heating from the voltage > regulator etc would not throw it off.) Not at this point. You're right, it needs to be the whole board. It's in a white flange mount ABS enclosure, and will have a port near the humidity, temperature, and baro sensors, which are all along one edge. It'll either be narrow slits, or a larger port covered with a metal mesh. It'll need to be kept out of direct sunlight and should be in a semi-protected location. A pagoda would be nice, but it was going to be too expensive to manufacture. Even using an existing pagoda would require making a custom enclosure to fit it, which would be a few thousand bucks for tooling. Maybe I'll do that in the future if I sell enough of these things. The files went off to the board house this morning... I should have something to show in a couple of weeks. Scott
