Fermion: SHT30 Digital Temperature & Humidity Sensor

This Digital Temperature & Humidity Sensor breakout board from DFRobot is based on the Sensirion SHT30 sensor IC. Thanks to Sensirion’s CMOSens® technology, highly integrated capacitive humidity sensing components and band-gap temperature sensing components, the SHT30 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 and more. 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.

The SHT30 is the low-cost version of the SHT3x series. It provides humidity accuracy ± 2%RH@10% RH~90% RH (at 25°C), and temperature accuracy±0.2°C@0°C ~65°C (typical). Selection Guide
