Hi to everyone,
I am currently building a wakeup alarm with an internal RH/Temp sensor. I am gonna 3Dprint the case for the whole system (which will go on its own pcb btw).
As I wrote in the subject...I need some idea to keep dust out and let moisture in for the sensor to measure.
The only idea I have had so far is to design 3/4 small openings on the bottom of the case and then glue some kind of cloth filter with an appropriate micrometric mesh size.
I am open to better ideas.
