(1) I2C read/write communication and pull up resistors current through SCL, SDA not included.
(2) Average current consumption while conversion is in progress.
(3) Heater operating range – 40°C to 85°C.
(4) Excludes hysteresis and long-term drift.
(5) Excludes the impact of dust, gas phase solvents and other contaminants such as vapors from packaging materials, adhesives, or tapes, etc.
(6) This parameter is specified by design and/or characterization and is not tested in production.
(7) The hysteresis value is the difference between an RH measurement in a rising and falling RH environment, at a specific RH point.
(8) Actual response times will vary dependent on system thermal mass and air-flow.
(9) Time for the RH output to change by 63% of the total RH change after a step change in environmental humidity.
(10) Drift due to aging effects at typical conditions (30°C and 20% to 50% RH). This value may be impacted by dust, vaporized solvents, outgassing tapes, adhesives, packaging materials, etc.
