Fermion: SHT35 Digital Temperature & Humidity Sensor

This Digital Temperature & Humidity Sensor breakout board from DFRobot is based on the Sensirion SHT35 sensor IC. Thanks to Sensirion’s CMOSens® technology, highly integrated capacitive humidity sensing components and band-gap temperature sensing components, the SHT35 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.

SHT35 is the high-end version of the SHT3x series. It provides humidity accuracy ±1.5%RH @ 0%RH~80%RH (at 25°C), and temperature accuracy±0.2°C@ -40℃-90℃ (typical).
