Package List: 1 x Temperature Humidity Sensor Probe Note: Note:The relative humidity of air is function of temperature, air temperature has a great impact on relative humidity, various compounds such as acids, alkalis, and salts have a significant impact on the physical properties of water steam. The following precautions should be taken when using:1. The temperature and humidity sensor should be installed in a place where the temperature is relatively stable and can best represent the measured ambient temperature and humidity.2. Avoid installing in places with drastic temperature changes.3. Avoid installing in areas with intense air flow.4. Avoid installing in dead corners where air does not flow.5. Avoid using in salt spray environments.6. Avoid using in corrosive gas environments.Working Conditions:The sensor performs normally within the recommended operating range. Long term exposure to conditions outside the normal range, especially when humidity exceeds 80%, may cause temporary signal drift (drift +3% RH after 60 hours). After returning to normal operating conditions, the sensor will slowly self recover to the calibration state. Prolonged use under abnormal conditions will accelerate the aging of the product.
