1、ACCURATE MEASUREMENT: This sensor probe has an accurate measurement performance, with a humidity accuracy ± 5% RH, and temperature accuracy ± 0.1 ℃. 2、COPPER, PLASTIC MATERIAL: Made of premium copper and plastic material, this sensor is strong and sturdy, wear resistant and can withstands harsh environments. 3、APPLICABLE SCENARIOS: Suitable for measurement of temperature and humidity of agricultural greenhouse, flowers, nursery, soil, etc. 4、EASY USE: This temperature sensor probe is small in size and light in weight that you can easily carry and install it for convenient use. 5、USE INDICATION: The sensor performs normally within the recommended operating range, and long term exposure to conditions outside the normal range, especially when humidity is greater than 80 percent, may cause temporary signal drift (drift+3% RH after 60 hours). When normal operating conditions are restored, the sensor will slowly self recover to the calibration state. Prolonged use under abnormal conditions will accelerate the aging of the product. 1 x Temperature Sensor Probe Item Type: Temperature Sensor ProbeMaterial: Copper, PlasticMode: FS400 SHT45Working Current: Less than 15mAHumidity Accuracy: ± 1.5% RHTemperature Accuracy: ± 0.1 ℃Working Voltage: 3.3VTemperature Measurement Range: -20 ℃ to 100 ℃Humidity Measurement Range: 0 to 100 percent RHCommunication Interface: I ² CWorking Conditions: -20 ℃ to 90 ℃, 0 to 99% RHStorage Conditions: -20 ℃ to 80 ℃, 0 to 95% RHShell: Copper, PlasticLine Length: Approx. 150cm / 59.1inProduct 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, reliability and long term stability;Matters Needing Attention:The 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 vapor. 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.Avoid using in corrosive gas environments.Working Conditions: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 can accelerate the aging of the product.
