Absolute Maximum Ratings

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such

conditions can adversely impact product reliability and result in failures not covered by warranty.

Recommended Operating Conditions

Important note: The HS300x-ML1 series sensors are optimized to perform best in the more common

temperature and humidity ranges of 10°C to 50°C and 20% RH to 80% RH, respectively. If operated outside of

these conditions for extended periods, especially at high humidity levels, the sensors may exhibit an offset. In

most cases, this offset is temporary and will gradually disappear once the sensor is returned to normal

temperature and humidity conditions. The amount of the shift and the duration of the offset vary depending on

the duration of exposure and the severity of the relative humidity and temperature conditions. The time needed

for the offset to disappear can also be decreased by using the procedures described in “Storage and Handling”.
