If the sensors are only 200m apart, readings should be similar, hyper local pollution gives irregular high peaks I would not expect structural differences. I would guess the other sensor...

Nice tests! I also have multiple kits (7), the pm2.5 values are pretty similar but I do have differences in pm10. My appoach for the humidity issue is to use...

Hi Roger, I use the sds011 sensor, the Dutch institute for health and environment (RIVM) recommends this sensor for citizen science initiatives. In the current 6 kits I use a...

I checked the link, it's quite a theoretical story! I used a more practical approach. My goal have solution that works the entire year, so the problem with solar power...

Still work in progress, unfortunately it's more complex than simple heating. Heating in general does improve the correlation with reference sensors (about +5%). The downsides are that you need a...

Check out https://amt.copernicus.org/preprints/amt-2019-422/amt-2019-422.pdf , much of the output is just calculated. In our project we use only the PM2.5 results of the SPS30. We prefer the SPS30 over the SDS011...

I had the same issue with one sensor, I just let it run to see what would happen. After about 8 hours it went back to normal. I cheched the...

That's more than 2 days... ☹

Good point! Would be nice to have an offset option for all sensors.
