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 vapor. The following items should be noted when using: <br>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. <br>2. Avoid installation in places where the temperature changes drastically. <br>3. Avoid installation in places where the air is flowing. <br>4. Avoid installing dead corners where air does not flow. <br>5. Avoid using it in a salt spray environment. <br>6. Avoid use in corrosive gas environments. <br>7. Avoid installing dead corners where air does not flow. <br> <br>Working Conditions: <br>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 (after 60 hours drift +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. <br> <br>Storage Conditions and Operating Instructions: <br>Humidity sensors are not ordinary electronic components and require ca
