Hello,
I'm looking for a temperature sensor which can give an error around 0.1°c for a human body temperature range. Firstly I’ve looked for a temperature sensor with an accuracy equal or above 0.1°c. But I’m not sure that I have to use this.
Example:
We take a sensor with a worst accuracy (3°c) but always with a resolution of 0.05°c. We calibrate the sensor around 35°c. The question is: around 35°c is the resolution becomes the precision? But only around 35°c, because we don’t know how the sensor behaves at another temperature. If we measure 35°c, the result has to be included in 34.9 and 35.1°c.
With a calibration with to points, we could correct the slope of the error and not only the offset like previously.
The question is: When I buy a sensor with accuracy around 5°c. After a calibration the precision means nothing? So the precision is just for the production of the sensor and for 10 sensors I could have 10 different results. Or maybe one day I can start my system and the sensor is wonky and again with a 5°c of precision?
