 There are many mounting options, your suggestion being one of them.  The PCB is not even necessary from a functional perspective.  You could mount the sensors with standoffs, or even just glue them into place.  But from a wiring perspective the PCB cleans things up a bit and the layout was just my own preference.  I encourage and expect people to modify to taste.

 Jon,sorry didn't see the second email.I had previously looked at the CO2 sensor & seen there were options for a moduleWith tube attachments. I presume you would then need to pump the air in!Have you thought about just putting a conformal coating on the circuit board &mounting it with PCB stand-offs.Perhaps make note of this option in the build instructions.Alan

 Ok, not really blowing on them.
In this case Alan, I will simply drill a bunch of small holes into the enclosure to allow air circulation.  I wasn't able to find a small enough ventilated enclosure that made sense.  This one happened to be perfect size for the PCB.

  Looks great Jon. How are you getting the air to flow across them in the enclosure? Alan
