SHT31-F is the standard version of the SHT3x series. It provides humidity accuracy ط¢آ±2% RH @ 0%RH~100%RH (at 25ط¢آ°C), and temperature accuracyط¢آ±0.2ط¢آ°C @ 0ط£آ¢أ¢â‚¬â€چط¦â€™-90ط£آ¢أ¢â‚¬â€چط¦â€™ (typical).
The SHT31-F chip features a PTFE membrane dedicated to protecting the sensor opening from liquids and dust according to IP67. It thus allows thesensor to work under harsh environmental conditions, where spray water and high exposure to dust might be challenging for accurate sensor performance. Due to minimal package volume and the membraneأ¢â‚¬â„¢s high water vapor permeability, the response time of the relative humidity and temperature signal is identical to the value achieved by the uncovered sensor. Although the membrane option provides perfect protection against water and dust ingress, it does not in general prevent contamination from volatile chemicals.
