Yes, both are syntactic sugar for the SI unit.
1 Pa = 1 N / m²
1 bar = 10⁵ Pa.
(1 bar happens to sound nice to old-schoolers, because it is slightly

That would even support a large measuring range, common sensors have
a resolution of 10-100 Pa. So unless you want to monitor a vacuum

At ${WORK} we frequently use single-digit milliTorr, as well as 1e-7
Torr or so, for lab measurements. I'm not sure that you want to support
sensors in that range; I'm just mentioning it in an attempt to quantify
a possible use case.
Take care,

LGTM - please make sure these are used as entropy sources, IIRC I
hardcoded the sensor types when I originally did

Until very recently I had never seen pressure in kPa. For atmospheric
pressure, the standard unit seems to be hPa. I realiz

Hi,
i'd like to have the functionality given by the diff below, before
cleaning up another diff making use of it.
with "# envstat -Td bmx280temp0 -i 1" i get output like:
Current Max Min Avg Unit
temperature:25.070 25.070 25.060 25.067
