Package List: 1 x Temperature Humidity Sensor Probe Note: Air relative humidity is a function of temperature, air temperature has a great impact on the relative humidity, acid, alkali, salt and other compounds have a significant impact on the physical properties of water vapor, should pay attention to the following matters: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 installation in places with drastic changes in temperature.3. Avoid installation in places with intense air flow.4. Avoid installation in the dead angle where the air does not flow.5. Avoid using in the environment with salt spray.6. Avoid use in corrosive gas environment.7. The power supply voltage range is 3.3V. The recommended power supply voltage is 3.3V. A 100nF decoupling capacitor is connected between the internal power supply and the ground. 9.2 serial clock input.8. The humidity sensor is not an ordinary electronic component and needs to be carefully protected. Users must take this seriously. Prolonged exposure to high concentrations of chemical odors can cause sensor readings to drift.9. The performance of the sensor is normal within the recommended working range. Long term exposure to conditions outside the normal range, especially when the humidity is >80percent , may cause temporary signal drift(drift after 60 hours +3percent RH). When the sensor is restored to normal working conditions, it will slowly recover to the correct state. Long time use under abnormal conditions will accelerate the aging of products.
