SEN0666 Barometric Pressure & Temperature Sensor

DFRobot SEN0666 Fermion Barometric Pressure and Temperature Sensor is an ultra-compact, industrial-grade environmental monitoring module designed for space-constrained applications requiring extreme durability. By integrating the next-generation Bosch BMP585 MEMS chip into the miniature Fermion form factor (19mm × 16mm), this digital altimeter breakout delivers laboratory-level absolute accuracy of ±0.3hPa and ultra-low noise (< 0.1Pa RMS) without occupying valuable PCB real estate. Distinct from standard sensors, the pressure sensing unit features a proprietary gel-filled cavity that provides robust protection against water, humidity, and chemicals. With a sleep current of just 2μA and support for I²C, SPI, and I3C interfaces, the DFRobot SEN0666 barometric board is the definitive solution for highly integrated devices such as smart wearables, micro-drones, and portable GPS trackers, where size, power efficiency, and environmental resistance are non-negotiable.
