SHT31 Digital Temperature & Humidity Sensor Breakout
This DFRobot SHT31 digital temperature and humidity sensor is based upon the Sensirion SHT31 sensor IC. Thanks to Sensirion’s CMOSens® technology, highly integrated capacitive humidity sensing components and band-gap temperature sensing components, the SHT31 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. 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.
SHT31 is the standard version of the SHT3x series. It provides humidity accuracy ± 2%RH@0% RH~100% RH (at 25°C), and temperature accuracy±0.2°C@ 0°C ~90°C (typical).
