- I am measuring the temperature of a metal plate using 4 thermal sensors.
- The sensor used is specified to have an accuracy of ±0.1°C.
If I have for example those readings:
The average of all sensors is: 20.45°C.
However how should I report the accuracy?
My intuition is that:
- The lowest reading (20.3°C) could be as low as 20.2°C because of the sensor reported accuracy.
- The highest reading (20.6°C) could be as high as 20.7°C.
- That covers an 0.5°C range.
So I would conclude that the accuracy of my sensors average is ±0.25°C
Is this correct?
