  1. 1 Tolerance figures describe the sensor manufacturer's production testing of the sensor IC, not complete-device accuracy. Contamination from VOCs and long-term drift are excluded. Typical values are based on ±2 standard deviations, meaning 95% of parts are within the typical figure.
  2. 2 Humidity drift assumes no contaminant exposure and recommended operating conditions.
  3. 3 The recommended storage temperature maximises battery lifetime. The survivable range is the limit the device can be stored at, not a recommendation.
