Mount a full sized Raspberry Pi upright, in a good position for use with the Pimoroni Enviro+ shield + PMS5003 sensor.  Optionally, an adapter is available for both this remixed stand and for the original PiZero stand (available at https://www.thingiverse.com/thing:4251492) to allow an articulating camera to be attached using parts from https://www.thingiverse.com/thing:4364785

If you want an environmental sensor that also has a camera, this is a pretty decent setup.  The Enviro+ AND the camera does work decently with relatively low (but acceptable) framerates.
