Table 1 Temperature sensor specifications.

Figure 2 Typical and maximal accuracy for temperature sensor in °C.

1 For definition of typ. and max. accuracy tolerance, please refer to the document “Sensirion Humidity Sensor Specification Statement”.

2 The stated repeatability is 3 times the standard deviation (3σ) of multiple consecutive measurement values at constant conditions and is a measure for the noise on the

physical sensor output.

3 Resolution of A/D converter.

4 Specified range refers to the range for which the temperature sensor specification is guaranteed.

5 Temperature response time depends on heat conductivity of sensor substrate and design-in of sensor in application.

6 Max. value is < 0.04°C/y.
