WebOct 4, 2024 · It will require calibration (say at room temperature and 0°C in an ice-water slurry. Sensitivity will be about -2mV/K so with a 5mV resolution ADC you’ll have 2.5 degrees C resolution, not great. If you connect it as a Vbe multiplier, say with 5:1, and average many measurements you might be able to get a usable resolution of about 0.5°C.
