This module mainly uses the SHT31 temperature and humidity sensor, which belongs to the SHT3X series temperature and humidity sensor. Compared with the temperature and humidity sensor of SHT2X series, the SHT3X series performs smarter, more reliable, and more accurate. They have access to more stronger functionality and higher signal processing capabilities.
At the same time, the SHT3X series offers some new features, such as enhanced signal processing, two unique and user-selectable I2C addresses, an alarm mode with programmable temperature and humidity limits, and communication speeds up to 1 MHz.
