Product Description
Product Description
The DFRobot Gravity: SHT31-F Digital Temperature and Humidity Sensor is a temperature humidity sensor module based on the Sensirion SHT31-F. It is designed for digital measurement of temperature and relative humidity and communicates via an I2C interface. The module supports a supply range of 3.3 to 5.5 V, allowing integration with common microcontroller platforms.
The sensor uses Sensirion CMOSens® technology with integrated capacitive humidity sensing and band-gap temperature sensing components. According to the manufacturer, it provides typical temperature accuracy of ±0.2 °C from 0 to 90 °C and humidity accuracy of ±2 %RH from 10 to 90 %RH at 25 °C. A PTFE membrane protects the sensor opening against liquids and dust to IP67, supporting operation in environments with spray water or elevated dust exposure.
