This is a housing for impWeather by Victor Carreño, for the "Give Your Hardware a Home" contest.
I got the idea for this design from old style wooden weather houses, with louvered sides for venting.
The housing was designed to sit on a table, shelf, or any flat surface. The main components, the Arduino board and battery, are stacked at the base of the housing. The DTH11 sensor is mounted in the center of the housing facing down, to prevent moisture from collecting on it. The mount is designed so that the DTH11 can be slid in from the back (left of the picture), and there is a stop on the right outer edge.
The battery is snapped and held into place with clips. Below the battery is the compartment for the Arduino board. The Arduino board is protected from most of the outside elements by a cover, between it and the battery. The cover is held in place using 2 screws.
The wires for the DTH11 sensor are routed to the Arduino board through 2 small access holes below the battery. The holes can be sealed with silicone sealant or left open.
The housing top is mounted to the bottom chassis using 3 screws. 3 long vertical posts on the housing top, fit into a channel on the bottom chassis, where screws from the bottom secure the housing, as shown in the cutaway photo. The louvers are an integral part of the 3 vertical posts.
