DFRobot SHT31 Digital Temperature and Humidity Sensor Breakout is based on Sensirion SHT31 sensor IC that features CMOSens® technology. This sensor offers high reliability and long-term stability with low power consumption, fast response, and strong anti-interference ability. The SHT31 sensor breakout features highly integrated capacitive humidity sensing components and band-gap temperature sensing components. This sensor breakout supports I2C communication and is compatible with 3.3V/5V controllers like Arduino, micro:bit, and ESP32. The SHT31 sensor breakout provides humidity accuracy of ±2%RH at 0%RH to 100%RH (at 25°C) and typical temperature accuracy ±0.2°C at 0°C to 90°C. This sensor breakout is ideal for use in urban environment monitoring, intelligent buildings, industrial automation, smart home, and other Internet of Things (IoT) applications.
