Item Type: Soil Temperature Humidity SensorMaterial: 304 stainless steel PlasticModel: FS304 SHT45Operating Current: Humidity Accuracy: ±1.5%RHTemperature Accuracy: ±0.1°COperating Voltage: 3.3VTemperature Measurement Range: -20℃ to 100℃Humidity Measurement Range: 0 to 100%RHCommunication Interface: I²COperating Condition: - 40°C to 125°C, 0 to 99%RHStorage condition: - 20℃ to 80℃, 0 to 95%RHHousing: 304 stainless steel IP67 Cable Length: Approx.150cm / 59.06in CautionAir relative humidity is a function of temperature, air temperature has a great impact on relative humidity, acids, bases, salts and other compounds have a significant impact on the physical properties of water vapour, the following matters should be noted when using:1. The temperature and humidity sensor should be installed in a place where the temperature is relatively stable and best represents the measured ambient temperature and humidity.2. Avoid installation in places where the temperature changes drastically.3. Avoid installation in places with intense air flow.4. Avoid installation in dead ends where the air does not flow.5. Avoid using in salt spray environment.Avoid using in corrosive gas environment.Operating conditionsThe sensor performs normally within the recommended operating range, see Figure 1. prolonged exposure to conditions outside the normal range, especially at humidity > 80%, may result in a temporary drift of the signal (drift of 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 ageing of the product.Package List：1 xSoil Temperature Humidity Sensor
