The temperature and humidity sensor should be installed in a relatively stable temperature, the most representative of the measured ambient temperature and humidity. 2. Avoid installation in places with drastic temperature changes. 3. Avoid installation in places where the air flows intensely. 4. Avoid installation in dead ends where air does not flowing. 5. Avoid using in the environment with salt spray. 6. Avoid using in corrosive gas environment. Operating conditions The sensor performs normally within the recommended operating range, refer to the figure. Long term exposure to conditions outside the normal range, especially at humidity levels greater than 80%, may cause temporary drift of the signal (+3% RH after 60 hours). Upon return to normal operating conditions, the sensor will slowly self revert to the corrected state. Prolonged use under abnormal conditions will accelerate the aging of the product.. Package List: 1 x Temperature Humidity Transmitter Probe Note: 1. Temperature humidity transmitter probe is not an ordinary electronic component and needs to be carefully protected. Users must take this seriously.2. Prolonged exposure to high concentrations of chemical odors can cause sensor readings to drift.
