DFRobot Gravity: SHT31-F Temperature & Humidity Sensor

DFRobot Gravity: SHT31-F Temperature and Humidity Sensor is based on Sensirion SHT31 sensor IC that features CMOSens® technology. This digital sensor offers high reliability and long-term stability with low power consumption, fast response, and strong anti-interference ability. The SHT31-F sensor features highly integrated capacitive humidity sensing components and band-gap temperature sensing components. This sensor supports I2C communication and is compatible with 3.3V/5V controllers like Arduino, micro:bit, and ESP32. The SHT31-F sensor provides humidity accuracy of ±2%RH at 0%RH to 100%RH (at 25°C) and typical temperature accuracy of ±0.2°C at 0°C to 90°C. The SHT31-F sensor features IP67 rating that protects the sensor opening from liquids and dust. This sensor is ideal for use in urban environment monitoring, intelligent buildings, industrial automation, smart home, and other Internet of Things (IoT) applications.
