Weather Station Upgrade

I’ve added an air quality monitor to my weather station. This uses a laser to measure the particle concentration between 0.3 to 10µm in the air. The sensor is the silver and black unit at the left, and has a small fan which sucks the air in from the outside via a small tube which you can just see going through the garage wall to the outside.

There is a more detailed explanation of the sensor Here

The output from this sensor are two values for PM2.5 and PM10, both measured in µg/m³. This graph shows the PM2.5 value for the last 24 hours – it’s still a bit high as the unit is still settling down:

You can see the results from this, and my other weather sensors, by viewing username ‘view’, password ‘view’. Click on the icons to see the graphs showing these inputs change.
