Outdoor temperature
Outside temperature sensor should be placed in shady, airy place 2m above
the ground. To achieve such conditions you need to either build a
meteorological cage or at least cover the sensor itself.
I decided to take a little bit different way - and used an air inlet located
on the north side of the house. At the other end of this air inlet (in the
room) non-return valve is installed (to make sure that we do not measure the
temperature of the room). In the same place I also installed
hygrometer, and
in the room to which this air inlet goes my
barometer is installed.
As temperature sensor DS18B20 is used.
Temperature read from the sensor:
owread 28.sensor_number/temperature12
To readings we can as usual add our favorite graphical presentation:
Personal Weather Station.

I use, and how do I use them.
