Specs for the weather station, for box building…
Main station is designed to sit on a 1-2" dia round pole. It has u-bolts to attach itself to that. It has to sit on top. It is shaped like a 3-pointed star, each arm is about 7" long.
The AQI sensor is 2.75 W x 4" L x 2.75 H. It has a little solar panel on top, so it also needs to sit in the sun. It doesn’t have any mounting hardpoints, but it has plenty of slots and holes for ziptying.
The instructions say the on-board batteries will last 2 years and I just ordered lithium AAs that should extend that. I think we don’t need land power, so no on-board electronics box.
