Fermion: BMP581 High-Precision Barometric Pressure & Temperature Sensor (Breakout, I2C/I3C/SPI, ±0.3hPa)

The Fermion BMP581 breakout is a high-precision barometric pressure and temperature sensor powered by Bosch low-noise sensing architecture. Featuring exceptional accuracy and ultra-low standby power, it suits makers, educators, and engineers building environmental trackers, weather stations, or altimetry projects.

High-accuracy pressure measurement

The onboard BMP581 delivers pressure sensing with an accuracy rating of ±0.3hPa. This level of precision enables reliable atmospheric monitoring and fine-grained elevation estimation.

Dual environmental data collection

This breakout measures both barometric pressure and ambient temperature on a single compact board. It simplifies sensor wiring and data collection across compact IoT and robotics builds.

Versatile digital interface support

The module includes hardware support for I2C, I3C, and SPI communication protocols. This flexibility allows easy integration with popular microcontrollers and development platforms.

Ultra-low power consumption

With a sleep current of just 2μA, the board minimises battery drain during idle states. It is well suited for portable data loggers and battery-operated field sensors.

Bosch low-noise architecture

Integrated Bosch low-noise sensing provides stable readings with reduced measurement jitter. This ensures clean data output even in dynamic operational environments.
