Question about bugs and the PA-II-SD
JupiterJoe:
Hey guys, I just received and installed my PurpleAir sensor and was wondering about bugs getting into the unit. We have a lot of bugs here in FL, and they go everywhere. I know that the open spaces in here would be welcoming to a wasps nest or whatever.
My question is, would accuracy be diminished if I were to attach a loose screen to the bottom of this? It would hang down and be very loose on the bottom as to not impede airflow.
ConligWX:
If I were in the same scenario as you, yes I think I would put some sort of screen over it.

I used a fish net and ziptied it on. Hopefully it doesn't impede airflow and lasts outside. :)

I would check readings with that on and off, it might impede particle flow giving false readings considering how dense it is.
If it does change readings, something like a metal screen that is small enough to prevent wasps but no smaller than necessary to stop them.
JupiterJoe:
I have been watching my sensor since I’ve put the net on compared to nearby sensors, and it seems to be pretty close. Sometimes a little higher, sometimes a little lower, but I think localized readings will always be a little different. So far it seems pretty good, but I do like your idea better for a cleaner, more permanent solution. I will keep my eyes open for a good open screen and maybe cut it so it fits the opening perfect.
Thank you for your thoughts!
