Features: 1High Accuracy: The temperature and humidity sensor probe is a cable type sensor. The sensor outputs calibrated digital signals in standard IIC format. With ultra high accuracy of 1.5% RH and 0.1 , ensuring high reliability and excellent long term stability. 2Strong Practicability: Can be used in monitoring in machine room, warehouse, construction site, concrete test block detection, agricultural greenhouse, flower nursery and soil temperature and humidity measurement. 3Strong Functionality: Fully calibrated, digital output, and I2C serial interface, easy to integrate. The relative humidity of air is a function of temperature. 4Lightweight and Compact: The temperature and humidity sensor probe has a small volume and light weight, making it easy to carry and install without occupying too much space. 5With 300cm Long Cable: The cable length is 300cm, without worrying about insufficient cable length, which can fully achieve your applicable range. Item Type: Temperature Humidity Sensor Probe Model: FS400-SHT35 Working Current: < 15mA Humidity Accuracy: 1.5% RH Temperature Accuracy: 0.1 Working Voltage: 3.3V Temperature Measurement Range: -20 ~ 100 Humidity Measurement Range: 0-100.0%RH Communication Interface: I2C Working Condition: -20 ~ 90, 0-99%RH Storage Condition: -20 ~ 80, 0~95%RH Casing: Stainless Steel, Plastic Line Length: Approx. 300cm / 118.11in Product Features: 1. Digitization, with a resolution of up to 14 bits. 2. Internal self calibration, no calibration required. 3. The close combination of temperature and humidity is convenient for dew point measurement. 4. Anti rain, dust, rust, high reliability and long term stability. Note: Relative humidity of air is a function of temperature, and 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. 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. Operating 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 +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 can accelerate the aging of the product. , 1 x Temperature Humidity Sensor Probe
