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 vapor. 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 flow
4. Avoid installing in dead ends where the air does not flow
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 >80%, may cause temporary signal drift (drift <3%RH 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:
1.The supply voltage range is 3.3V, the recommended supply voltage is 3.3V.
2.Connect a 100nF decoupling capacitor between the FS400 SHT4X internal power supply and the ground wire.
3.Prolonged exposure to high concentrations of chemical odors can cause sensor readings to drift.
