Introduction
This DFRobot SHT31-F digital temperature and humidity sensor is based upon the Sensirion SHT31-F sensor IC. Thanks to Sensirions CMOSens® technology, highly integrated capacitive humidity sensing components and band-gap temperature sensing components, the SHT31-F offers high reliability and long-term stability with low power consumption, fast response and strong anti-interference ability. The sensor supports I2C communication, and is compatible with 3.3V/5V controllers like Arduino, micro:bit, ESP32. It is easy to achieve precise and high-reliability temperature and humidity sensing for urban environment monitoring, intelligent buildings, industrial automation, smart home and other Internet of Things applications.
SHT31-F is the standard version of the SHT3x series. It provides humidity accuracy 2% RH @ 0% RH~100% RH (at 25°C), and temperature accuracy 0.2°C @ 0°C ~90°C (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 the sensor 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 membranes 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.
