SHT31-F : Humidity and temperature sensor

Sensirion SHT31-F Humidity & temperature sensor with dust protection

This SHT31-F breakout is an I2C temperature and humidity sensor on the Sensirion SHT31-F sensor IC (from Switzerland). This sensor integrates a capacitive humidity sensing components and band-gap temperature sensing components. The SHT31-F will offers high reliability and stability on long-term measurements while keeping the power consumption quite low. SHT31F is knwon for its fast response and strong anti-interference ability.

The sensor supports I2C communication and can be powered with 3.3V or 5V. So it is a suited sensor for Arduino, Raspberry-Pi, Pyboard, PYBStick, Micro:bit, ESP32.

SHT31-F is the standard version of the SHT3x series. It provides humidity accuracy +/-2% RH @ 0% RH~100% RH (25°C) and temperature accuracy+/- 0.2°C @ 0°C ~90°C (typical).
It is easy to achieve precise and high-reliability temperature and humidity sensing. This sensor is suited for urban environment monitoring, industrial automation, smart home, building monitoring and any IoT applications.
