Open Source Air Quality Sensor housing

Open Source Air Quality Sensor housing project being built for use in Birmingham. Uses a Raspberry Pi W Zero and a Trinket plus a custom "Hat" to connect all of the sensors. Room in the base for batteries and other necessities as well as mounting holes to tie it to a bracket. Uses about .313Kg of plastic to print one set of all pieces.

Suggest painting with white paint any surface that would be subject to sunlight to prevent plastic degradation. Doing testing with ESUN white PETG filament.
2 new louvers published to use with Honeywell HPMA115S0 Dust Particulate Laser interferometer

My current design uses Base_Pycom.v2, Louver_top.v2, Louver_HPMA.v2 and Louver_L4.v3

Control system and hardware still being developed.
Two versions of sensors have been built using this. Githubs for this is located at
