Features ​Function: The temperature and humidity sensor probe is a cable-type sensor in the digital temperature and humidity sensor series. The sensor outputs a calibrated digital signal in standard I2C format. DFN package for reflow soldering. Digital output, I2C interface. Cost Effective: The world's most advanced temperature and humidity sensors are used as the core components to ensure high reliability and long-term stability of excellent performance. It has the advantages of good quality, high protection level, ultra-fast response speed, strong anti-interference ability, and high cost performance. It is waterproof, dustproof, rust-proof and corrosion-resistant. Advantages: The sensor includes an improved capacitive humidity sensing element and a standard bandgap temperature sensor element for improved performance. Fully calibrated, excellent long-term stability. Low power consumption, low cost and small size. Wide Application: It can be used in computer room monitoring, HVAC, weather station, warehouse, construction site, concrete test block detection, agricultural greenhouse, flower nursery and soil temperature and humidity measurement. Note: ​The sensor performs normally within the recommended operating range. Long-term exposure to conditions outside the normal range, especially at >80% humidity, may cause temporary signal drift (+3% RH after 60 hours). When returning to normal operation, the sensor will slowly return to the calibrated state. Prolonged use under abnormal conditions will accelerate the aging of the product.

Package List: 1 x Temperature and Humidity Sensor 1 x Line Mark Precautions: 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 vapor. 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 flowing. 4. Avoid installing dead corners where air does not flow. 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 flow. 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 vapor will cause the sensor reading to drift. Package List
