Assembling the air quality monitor

We wanted our air quality monitors (AQMs) to be weatherproof, so I used cheap, dollar-store tupperware enclosures with snap-tight lids. Each was $1.50 CAD.

The SDS011 can be connected to a short hose for enclosed use. I used some hose I had around the house from making beer.

The tupperware needs three holes: one for the intake, one for the air outlet, and one for the power cable. I burned small holes in the sides of the case with a heated screwdriver, pushed the cables through, and sealed the holes with caulking.
