Fermion: SHT31 Digital Temperature & Humidity Sensor (Breakout, I2C)

The Fermion SHT31 Digital Temperature and Humidity Sensor breakout board provides precise environmental sensing over an I2C interface. Built around the SHT31-DIS sensor, it delivers reliable climate measurements in a compact form factor. It is well suited to makers, students, and engineers developing weather stations, terrarium controllers, and automation systems.

High-accuracy temperature monitoring

The onboard SHT31-DIS sensor measures temperature with an accuracy rating of ±0.2°C. This level of precision provides dependable thermal readings for demanding monitoring applications.

Precise relative humidity measurement

Relative humidity is tracked with a high accuracy of ±2%RH. This ensures accurate environmental data collection for indoor climate and greenhouse control systems.

Digital I2C communication

The breakout uses a standard I2C digital interface to communicate directly with microcontrollers. This simplifies wiring and eliminates the analogue signal noise associated with traditional sensing elements.

Compact breakout format

The module features a small footprint designed for easy prototyping on breadboards and integration into tight enclosures. It offers an accessible way to add SHT31-DIS sensing capabilities to any project.
