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.
