<![CDATA[PM2.5 without SHT]]>Hello,
I got a PM2.5 module and a core. Using the m5flow / blockly there are only PM2.5 with SHT20 or SHT30 to choose - then I always get the message that SHT20 or SHT30 sensor is missing. Is there any possibility to choose PM2.5 + ENVpro sensor (wich I already have)??

Kind regards, Gernot

Maybe consider using Arduino as I had no troubles reading out the SHT30 on my PM2.5 with that.

the sensor SHT20 or SHT30 is in the gray base of the PM2.5 Air Quality Kit or PM2.5 Air Quality Kit（SHT30)

From what I can tell UIFlow doesn't seem to support the PM2.5 module (w/o base).

That said, the base seems to be available a separate item.

Thanks
Felix

both versions do not work. I always get the error message "SHT20 Sensor maybe not connect" or "SHT30 Sensor maybe not connect"
it seems there is no such sensor in the PM2.5
