DFRobot SEN0667 Fermion Barometric Pressure Sensor

DFRobot SEN0667 Fermion Barometric Pressure Sensor is powered by Bosch Sensortec's BMP581 high-performance barometric pressure sensor chip. Compared to its predecessors, the BMP581 represents a quantum leap in accuracy, temperature stability, and power efficiency. With an absolute accuracy of ±0.3hPa and minimal offset, this sensor precisely detects minute altitude changes, capable of distinguishing floor levels or monitoring liquid level variations.

Featuring a compact footprint and comprehensive support for I2C/I3C/SPI interfaces, this module is the ideal choice for drone altitude hold, indoor navigation assistance (floor detection), and outdoor fitness trackers. For projects demanding superior data quality within a strict budget, the DFRobot Fermion BMP581 offers an uncompromising solution.

This module operates at 3.3V logic. A logic level converter is required when using with 5V microcontrollers (e.g., Arduino Uno).
