DFRobot Fermion BMP585 High-Precision Barometric Pressure and Temperature Sensor (±0.3 hPa) - I2C/SPI/I3C Module

The module operates from a supply voltage of 1.7V to 3.6V DC. It is designed for direct compatibility with 3.3V logic systems commonly found on development platforms like Arduino, ESP32, and Raspberry Pi. Ensure your power source is within this range for proper sensor functionality and to avoid damage.

The module supports three digital communication protocols: I2C, SPI, and the newer I3C standard. You can select your preferred interface by configuring the module's solder jumpers or through software commands. The default address for I2C communication is typically 0x77, but it is configurable to avoid bus conflicts.

The Bosch BMP585 sensor provides an absolute pressure measurement range from 30 kPa to 125 kPa. Its typical absolute accuracy is ±0.3 hPa (hectopascal), which translates to high precision for altitude tracking and atmospheric monitoring. The integrated temperature sensor supports environmental compensation for these readings.

Yes, its ultra-low power consumption makes it ideal for portable devices. The sensor draws approximately 200µA during active measurement and can be put into a sleep mode consuming only about 2µA. This power profile, combined with the configurable measurement rate and FIFO, maximizes battery life in wearables and IoT nodes.

The BMP585 is factory-calibrated, and individual calibration coefficients are stored in its internal ROM, so no user calibration is typically required for basic operation. For optimal performance, you can utilize its built-in features like the IIR filter and oversampling settings, which are configurable via the communication interface to suit specific application noise and data rate requirements.
