Topic: PM2.5 Mounting

[ALEEF02]

I just purchased myself one of the pm2.5 monitors, since they just came back in stock. I want to monitor the outdoor air quality, but I have read that high humidities can severely affect the readings. I was most likely going to mount it under my overhang to prevent it from getting wet, but consequently that will also cause the solar panel to get little to no sunlight. Is there a better way to mount it so that I can get the most accurate readings? Thanks!

I am given to understand it is not necessarily the sensor gets wet is the issue, high humidity is the issue. Micro water drops form and the unit counts them as particulates. Mine is mounted on the top of a 4x4 in direct sun.

Yes, it's designed to survive rain. But don't expect accurate reading on a foggy day.

Yep just don't expect wonders with this sensor. Truly great PM2.5 sensors will first heat up the air to get rid of moisture and not count them as particles.

Can I see a picture of your set up?

Also, I just looked at your ambient weather dashboard. How did you get that sun and moon tile?

Edit your device in Ambientweather.net and add your location. Then sun/moon tile will show up automatically. This is a new feature.

The sensor is mounted to the top of a 4x4 fence post in direct sunlight.
