The ideal enclosure for keeping the weather sensors is the Stevenson Screen. A Stevenson screen is an enclosure to shield meteorological sensors against precipitation and direct heat radiation from outside sources, while still allowing air to circulate freely around them.

I have designed a 3D printed Stevenson screen to keep the weather sensors and PCB board. The enclosure has the following parts:

1. Base part

2. 4 x Middle Rings

3. Middle Cover  ( Separate the Solar panel from the  PCB chamber )

4. Top Cover ( above which a 130 mm circular solar panel will be mounted )

The whole idea is to stack all the above parts one above the other so that the inside chamber will be well-ventilated from the outside. 

The above parts will be assembled by using 4x M4 rods, it can also be 3D printed.
