hello all,
since this morning our SDS011 sensors are sending extra low readings…
these are from two different places.
the one is the first one i bought from the Polish site.
the other is from aliexpress…
are your sensors working fine ?
hahaha… maybe all PMs are charged electrically and went to surfaces…
these are my sensors with readings of livingroom, bedroom, etc… 
It is indeed possible to get readings like this. My sensor did the same thing yesterday (I’m in Thuringia, Germany). Even my local weather service shows similar data. It depends on the weather - with the right conditions the values can drop to such low levels (wind, weather conditions).
