Temperature accuracy of the MLX90621

10.1.

All accuracy specifications apply under settled isothermal conditions only.

Furthermore, the accuracy is only valid if the object fills the FOV of the sensor completely.

Figure 26: Absolute temperature accuracy for the central four pixels

All accuracy specifications apply under settled isothermal conditions only.

NOTE:

The accuracy is specified for the four central pixels. The accuracy of the rest of the pixels is according to the

uniformity statement

As a result of long term (years) drift there can be an additional measurement deviation of ± 3°C for object

temperatures around room temperature.
