Luftdaten Particle Monitor Enclosure with Bug Filter and Lip seals

thingiverse

A compact Particle Monitor Station Enclosure designed to keep both rain and bugs out, while minimizing recirculation and maximizing responsiveness to short-term variations. A careful design ensures that the air sampling path and exhaust path are separated, with a short and low-volume sampling path for better results. A word of caution: spiders have been known to make their homes in inlet tubes, and webs can easily become particle filters. This was discovered firsthand by a group in Sheffield, England. The hardware required includes: 9 M2.5 x 5mm pan head screws for board mounting 6 M3x12mm pan head screws for the lid 4 M3x12mm pan head screws for the lid Stainless steel external screws are recommended for durability. A length of tube is needed to fit over the SDS011 sensor inlet, cut close to the bug filter (about 2mm) to ensure outside air sampling. The Mount attaches simply by screwing onto the back and features four lugs for wall mounting on screws, as well as slots for tying to posts and drainpipes. The design allows for custom mounts to be added at a later stage. There is also room for designing a battery pack that can mount on the rear screw holes - watch this space. The author hopes you find their design helpful and encourages sharing it if it proves useful.
