Calibrating at 25°C will improve accuracy to
Calibration at 3 points, -40°C, 25°C, and 125°C will improve accuracy to ± 2.5°C. Once calibration has
been completed, the user will need to calculate the slope for both hot and cold. In application code, the
user would then calculate the temperature using
temperature is above or below 25°C. Once determined if the temperature is above or below 25°C, the user
can recalculate the temperature using the hot or cold slope value obtained during calibration.
