Feature:1. Excellent Chip: The temperature and humidity sensor probe uses an excellent chip from the for 4X series, with low power consumption and high accuracy, ideal for mobile and battery operated applications.2. 14 Bit Resolution: Temperature and humidity sensor probes with up to 14 bit resolution and filter membrane provide additional particle protection for powerful use.3. Relative Humidity: Temperature and humidity sensor probe with fully calibrated, digital output, I2C interface, I2C serial interface is easy to integrate. Relative humidity of air is a function of temperature.4. Light and Compact: Temperature and humidity sensor probe is small and light, easy to carry and install, does not take up too much space.5. Multiple Use Sites: Temperature and humidity sensor probe can be used in weather stations, warehouses, construction sites, concrete test block inspection, agricultural greenhouses, flowers, nurseries and soil temperature and humidity measurements.Specification:Item Type: Temperature Humidity Sensor ProbeModel: FS400 SHT41Operating Current: Less than 15mAHumidity Accuracy: 2%RHTemperature Accuracy: 0.2Working Voltage: 3.3VTemperature Measurement Range: -20-100Humidity Measurement Range: 0-100%RHCommunication Interface: ICWorking Conditions: -20-900-99%RHStorage Conditions: -20-80, 0-95%RHCase: Copper, plasticWire Length: Approx. 150cm / 59inFeatures1. Digital with resolution up to 14 bits;2. Internal self calibration, no calibration required;3. Close integration of temperature and humidity for easy use in dew point measurement;4. Showerproof, dustproof, rustproof, high reliability and long term stabilityCautionAir 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 vapors, 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 represents the measured ambient temperature and humidity.2. Avoid installation in places where the temperature changes drastically.3. Avoid installation in places where the air flowing intensely.4. Avoid installation in corners where the air does not flowing.5. Avoid using in an environment with salt spray.6. Avoid using in corrosive gas environment.Operating conditionsThe sensor performs properly within the recommended operating range. Long term exposure to conditions outside the normal range, especially at humidity > 80%, may cause temporary drift of the signal (drift and 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 aging of the product..Package List:1 x Temperature Humidity Sensor ProbeNote:1. Humidity sensor probe is not ordinary electronic components and need to be carefully protected.2. The supply voltage range is 3.3V and the recommended supply voltage is 3.3V.3. The 9.2 serial clock input is connected with a 100nF decoupling capacitor between the internal power supply and ground.
