I think pressure needs to be provided in Pa not hPa - it is currently showing as 10.04 hPa on the sensor.community site.

Readings from the Enviro Urban's particulate sensor (Garden) seem to be tracking quite a bit higher (and with more variance) than the ones from my Raspberry Pi/Enviro+ combo (Street), and other sensors in the surrounding area.
