Product description: SHT31-F - digital temperature and humidity sensor I2C
The Sensirion SHT31-T sensor is based on the Sensirion SHT31-T sensor chip. It is a product of DFRobot, which has I2C communication. It works perfectly with 3.3 V / 5 V controllers of Arduino, micro:bit, ESP32 type. Its measuring range is very wide. For temperature it isfrom -40°Cto 125°C(with measurement accuracy of ± 0.2°C) andfor humidity measurement from 0% to 100% RH (withaccuracy of ± 2% RH).The sensor has automatic calibration, whose precision is at a high level. In addition, it consumes little energy, but still remains resistant to interference. The installed dustproof IP67 foil additionally protects the module against external factors.

Sensor outputs
The module is equipped with special leads (soldering fields) to which goldpin - 2.54 mm raster (included in the kit) connectors are soldered. Thanks to them it is possible to connect the circuit with acontactplateorwith the main component, e.g. Arduino. Additionally, a connection cable (Gravity-4P I2C / UART) is included in the set.
