Outside/Inside Temperature Sensor location

["Neil Wrightson" <neilw@xxxxxxxxxx>]

Hi,

I'm looking at putting some 1wire/ibutton temperature sensors in and I'm
wondering where is the best location for the sensors.

Outside

Just mounting on the side of the house or garage wall would not do due to
the possible heating or cooling effect of the brickwork.

Even putting it a short distance i.e.300mm of the brick work. It would
still
be affected by radiated heat.

Putting it in the middle of the yard where there is no shade sounds ok but
then how? Sky hook? And it also would then be affected by the direct
radiated heat from the sun, making it feel hotter than it actually is.

Inside

Same problem with inside, picking up the ambient room temperature without
being affected by the internal wall temperatures, sometimes the actual
walls
can be substantially cooler/hotter than the air temp. Also what height,
again there can be quite a few degree's C difference between the
temperature
300mm of the floor to 300mm of the ceiling.

Where is the ambient temperature?

Regards,

Neil Wrightson.
