Table 3 Maximum Operating Conditions

Figure 3 Humidity and Temperature Operating Range

The sensor should operate at peak condition less than 10% of the operating life. Exposure to absolute maximum

humidity/temperature conditions for extended periods may temporarily induce an offset on RH measurement (+5%RH above

accuracy specifications, which will recover over time) and accelerate its ageing.
