TIP #13 Reading A Sensor With Higher
Accuracy – A/D Method
NTC (Negative Temperature Coefficient) sensors
have a non-linear response to temperature
changes. As the temperature drops, the amount
the resistance changes becomes less and less.
Such sensors have a limited useful range because
the resolution becomes smaller than the A/D
resolution as the temperature drops. By changing
the voltage divider of the Rsen, the temperature
range can be expanded.
To select the higher temperature range, GP1
outputs '1' and GP2 is set as an input. For the
lower range, GP2 outputs '1' and GP1 is
configured as an input. The lower range will
increase the amount the sensor voltage changes
as the temperature drops to allow a larger usable
sensor range.
Summary:
High range: GP1 output '1' and GP2 input
Low range: GP1 input and GP2 output '1'
