Notes:

1.

Recommended humidity operating range is 20 to 80% RH (non-condensing) over 0 to 60 °C. Prolonged operation

beyond these ranges may result in a shift of sensor reading, with slow recovery time.

2.

The TH02 has a nominal output of 16 codes per %RH, with 0h0000 = –24%RH.

3.

Excludes hysteresis, long term drift, and certain other factors and is applicable to non-condensing environments only.

See section “4.2. Relative Humidity Sensor Accuracy” for more details.

4.

May be impacted by dust, vaporized solvents or other contaminants, e.g., out-gassing tapes, adhesives, packaging

materials, etc. See section “4.10. Long Term Drift/Aging”.

5.

Time for sensor output to reach 63% of its final value after a step change.
