I made the case for the impWeather unit from Victor Carreno's design of a wifi weather station for the home. I wanted to design the case to be weather resistant but not quite rain proof, and to allow easy maintenance of the internal electronics components.
It has a lip on the cover to help keep moister out. Near the top of the front cover, below the mounting slot, there are several small square holes (entry port) to allow atmosphere into the unit so the DTH11 sensor can measure temperature and humidity. The entry port is designed so that if water droplets come into contact with the case, the droplets won't enter into the case as long as it's mounted upright. If a small amount of moister enters the case, it will exit two small weep holes located at the bottom of the case.
The case cover is held in place with 4 small stainless steel screws at the corners. The internal electronic components are held in place with small plastic walls, which is part of the case bottom. When the cover is mounted and secure, plastic features protruding from the cover "hold" the components in place. The design is intended to allow for easy maintenance of the components.
I'm sure I may have missed a few design features... but I'm not perfect :)
