Hallo together,

i haved configured a SPS-30 Particular Sensor, everything works fine, only the Values are to high.

here the Values:

Sensirion SPS30 <1µm Weight concentration 13953.07 µg/m³
Sensirion SPS30 <2.5µm Weight concentration 92259.02 µg/m³
Sensirion SPS30 <4µm Weight concentration 154068.61 µg/m³
Sensirion SPS30 <10µm Weight concentration 188068.23 µg/m³
Sensirion SPS30 <1µm Number concentration 23566.72 #/m³
Sensirion SPS30 <2.5µm Number concentration 103626.62 #/m³
Sensirion SPS30 <4µm Number concentration 118731.16 #/m³
Sensirion SPS30 <10µm Number concentration 122259.69 #/m³

here the yaml:

Have someone an idea what can be wrong.

many thanks to all, gagaxxl

I found my mistake. Wrong Voltage, this Values came with 3.3V. With 5V ist everything OK
