DFRobot Fermion SHT35 Digital Temperature & Humidity Sensor Breakout Board - I2C Interface

The board supports a wide input voltage range from 2.15V to 5.5V DC. It includes onboard regulation and level shifting, making it directly compatible with both 3.3V and 5V microcontroller logic levels without requiring external components.

Connect the board using the standard I2C interface: VCC to your board's 3.3V or 5V pin, GND to ground, SDA to the corresponding I2C data pin (e.g., Arduino A4 or ESP32 GPIO21), and SCL to the I2C clock pin (e.g., Arduino A5 or ESP32 GPIO22). The included header pin simplifies wiring.

The integrated Sensirion SHT35 provides high accuracy with ±0.2°C for temperature and ±1.5% relative humidity. It features a fast response time, typically within a few seconds for humidity, and offers excellent long-term stability with auto-calibration, minimizing drift over time.

Yes, the SHT35 sensor supports two selectable I2C addresses via its ADDR pin. This allows you to connect up to two sensors on the same I2C bus without address conflicts, which is useful for differential or multi-point environmental monitoring setups.

Yes, the SHT35 chip is designed for high reliability and features strong anti-interference performance. The breakout board provides easy mounting. For harsh outdoor conditions, consider adding a protective enclosure to shield the sensor from direct water exposure and contaminants.
