DFRobot 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.
