PM10 in ecowitt WH41 sensor?

[Graham Eddy]

fiddling with SDR trying to find some other sensor, i notice the following from rtl_433:

time      : 2021-01-24 00:02:08

model     : Fineoffset-WH0290                      ID        : 4

2.5um Fine Particulate Matter: 8 ug/m3             10um Coarse Particulate Matter: 9 ug/m3

Integrity : CRC

which clearly says the ecowitt WH41 is transmitting PM10 value as well as PM2.5

i don't see the PM10 value appearing in WH41 ‘manual’, nor in gary’s gw1000 driver. is there some way to extract this PM10 value other than via SDR?

Not via the GW1000 API there isn’t. It does not show in any of the raw sensor data that is returned from the GW1000.

Hi

the GW1000 doesn't receive (or at least doesn't process) any pm10 data from the WH41, even though that one may send out such data.
If you want clarity, send an email to Lucy (sup...@ecowitt.com) and ask your below question.

Would be interesting to know what they have to say.

The WH0290 is only a display for PM2.5 data from a WH41 or WH43.
