1.1 Recommended Operating Condition

The sensor shows best performance when operated within recommended normal temperature and humidity range of 5 °C

– 60 °C and 20 %RH – 80 %RH, respectively. Long-term exposure to conditions outside normal range, especially at high

humidity, may temporarily offset the RH signal (e.g. +3%RH after 60h kept at >80%RH). After returning into the normal

temperature and humidity range the sensor will slowly come back to calibration state by itself. Prolonged exposure to

extreme conditions may accelerate ageing. To ensure stable operation of the humidity sensor, the conditions described in

the document “SHTxx Assembly of SMD Packages”, section “Storage and Handling Instructions” regarding exposure to

volatile organic compounds have to be met. Please note as well that this does apply not only to transportation and

manufacturing, but also to operation of the SHT3x-DIS.
