Checking of Remarkably High Values

I often see sensor #57231 showing > 600 PM10 values, which I find remarkably high for that location in Switzerland. I suppose it’s just possible that the local flooring company location is really putting that much PM in the air, but I very much doubt it.

Do such values ever get queried by Sensor.Community? Maybe the submitter has a problem with their sensor? Or maybe they really are living in such a dangerous situation? In either case, does an email get sent out to question such outlier values?

It is basically an issue. We promised never to send any Email and we never do (except for the automatic Email for deconnection). The user has to take care of its own sensor… Or maybe he smokes every hour next to the sensor…
But I thought we had implemented to filter sensors in such a situation.

This is just a casual observation, but I noticed that (heavily) malfunctioning sensors tend to show measurements as a flatline and ovelapping pm2.5 and pm10 values. I would bet that it is close to some emission source. Although that’s problematic in itself.

Or maybe it’s an indoor sensor which is falsely declared as outdoor sensor? I had to learn that indoor sensors are not displayed at the map, which means, that there is some wrong incentive to delare indoor as outdoor sensors, if you want it displayed.

By the way, just to change this wrong incentive I would suggest to display indoor sensors, too, but with a marking as indoor sensor. I understand the problem with that, as it is a costly help displaying only private data, but I would still vote for displaying marked indoor sensors.

Thanks to everybody!

P.S.: I myself don’t have a problem with that. I have an declared indoor sensor anddon’t need it displayed on the map. I am not talking about my personal interest.

I am still not sure about the conditions. Please check @pjg and @bertrik answers in my post: display-sensor-on-map-sensor-community-and-using-an-air-quality-lamp-from-the-project-stofananas-together-with-a-sensor

Maybe you could add an option in the T&Cs to be informed when the air conditions are looking dangerous. Personally I would like to know if I should avoid breathing. Or if my sensor has developed a fault.

You Mean this?
