Specification: Item Type: Sensor Probe Model: FS400 SHT40 Operating Current: &lt;15mA Humidity Accuracy: ±3% Temperature Accuracy: ±0.2°C Operating Voltage: 3.3V Temperature Measurement Range: -20 degrees Celsius to 100 degrees Celsius Humidity Measurement Range: 0 to 100% Communication Interface: I²C Operating Condition: - 20°C to 90°C, 0 to 99% Storage condition: - 20 degrees Celsius to 80 degrees Celsius , 0 to 95% Housing: Copper and plastic Cable Length: Approx.150cm / 59.06in Features: 1. Digitization, the resolution is 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 shower, dustproof, rust proof, high reliability and long term stability Air relative humidity is a function of temperature. Air temperature has a great influence on relative humidity. Acids, alkalis, salts and other compounds have a significant impact on the physical properties of water . The following matters should be paid attention to 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 places with intense air 4. Avoid installing in dead ends where the air does not 5. Avoid use in salt spray environments 6. Avoid use in corrosive gas environments Working conditions The sensor performs normally within the recommended operating range, see Figure 1 Long term exposure to conditions outside the normal range, especially at humidity &gt;80%, may cause temporary drift drift &lt;3% after 60 hours When returned to normal operating conditions, the sensor will slowly return to the corrected state Prolonged use under abnormal conditions will accelerate the aging of the product Package List: 1 x Sensor Probe Note: <div>1.The supply voltage range is 3.3V, the recommended supply voltage is 3.3V.</div><div>2.Connect a 100nF decoupling capacitor between the FS400 SHT4X internal power supply and the ground wire.</div><div>3.Prolonged exposure to high concentrations of chemical odors can cause sensor readings to drift. </div>
