Relative humidity of air is a function of temperature. Air temperature has a great influence on relative humidity. Various compounds such as acid and alkali salts have a significant impact on the physical properties of water. The following items should be noted when using: 1. The temperature and humidity sensor should be installed in a place where the temperature is relatively stable and most representative of the measured ambient temperature and humidity. 2. Avoid installation in places where the temperature changes drastically. 3. Avoid installation in places where the air is ing. 4. Avoid installing dead corners where air does not . 5. Avoid using it in a salt spray environment. 6. Avoid use in corrosive gas environments. 7. Avoid installing dead corners where air does not . Second, working conditions: The sensor has normal performance within the recommended operating range. Long-term exposure to conditions outside the normal range, especially at humidity >80%, may result in temporary signal drift (drift after 60 hours +3% RH). When returning to normal After the working conditions, the sensor will slowly return to the calibration state. Prolonged use under abnormal conditions will accelerate the aging of the product. Third, storage conditions and operating instructions: Humidity sensors are not ordinary electronic components and require careful protection. This must be taken seriously by users. Prolonged exposure to high concentrations of chemical smell will cause the sensor reading to drift
