Problem:
Temperatures do not match if
units are placed next to each other.
Solution:
Each temperature sensor is
manufactured to be accurate to within 2
degree plus or minus and under normal
conditions. It is possible for two
temperature sensors to be as much as 4
degrees different. The difference can be
exaggerated further because the temperature
sensors are designed for different working
environments. The indoor sensor is less
responsive to ambient air currents because of
the shielding effect of the indoor
temperature station’s case. In addition, the
casing can act as a heat sink to absorb and
store heat from external sources (i.e.
handling of the case or radiant heat). In
addition, the much greater range of the
outdoor temperature sensor requires a
different calibration curve than the indoor
range. Error is usually greater at the extreme
ends of a range, making it harder to compare
different ranges with different curves. Under
non-laboratory conditions, it is difficult to
