BME680 IAQ Measurements

1

We installed two IAQ Sensors with our Routers in the City about 4km apart and they are showing similar results.
What I dont understand is why the Air quality is getting worse at night and better in daylight…

At about 10:00 on both the Air quality is getting better.

Oh it is the absence of Wind at night that leads to accumulated pollutants. :point_up:
