I have an Air Monitoring HAT (Wiki · sbcshop/Air-Monitoring-HAT Wiki · GitHub) that has a PMSA003 sensor. Does anyone know whether this can simply be combined with the Enviro+?
The Enviro+ pinout is here,
Enviro Plus at Raspberry Pi GPIO Pinout
I “think” it will work if nothing is plugged into the PMS sensor plug on the Enviro+. I can’t 100% guarantee it though.
The only other thing to make sure is that the OLED on your hat isn’t using an i2c address that conflicts with those used by the Enviro+.
