Folks,
I have the PMS5003 Particle Sensor and have it successfully attached to my weather station. I am now looking to install it on a wall outside rather than by my open window ledge.
Obviously it is not weather secure so I have decided to re model a fridge food container to house it. (SImilar to the Airlink unit with a section at the "bottom" of the container removed)
My questions are:
1) Does the air flow from large aperture to the four small holes. I believe it does as I have tried with the smoke from a match but because the flow rate is so low it wasn't conclusive.
2) Having watched a video of a strip down of one of these units for clearing and seeing the dust inside the unit I wanted to know whether it would be better to mount it with the exit holes at the bottom of the unit (hopefully reducing the amount of dust settling on the photo diode)
Any comments?
