BMP390 in Bosch BME280 / BMP280 Family
The BMP390 is a high-performance barometric pressure sensor from Bosch Sensortec, engineered for precise altitude tracking and indoor navigation. Building on the success of the BMP280, it offers significantly improved stability and lower noise levels. This sub-family provides industrial-grade accuracy in a compact 2.0 x 2.0 x 0.75 mm³ LGA package, utilizing 24-bit resolution to deliver reliable vertical position data for consumer electronics and industrial IoT platforms requiring sub-meter precision.
Variants in This Sub-Family
While the BMP390 serves as the primary high-performance variant, the sub-family is characterized by specific optimizations for noise levels and power efficiency. Differences typically involve factory calibration parameters and sensitivity ratings. It maintains software compatibility with other Bosch pressure sensors, but focuses on a more robust MEMS design compared to the general-purpose BMP280, ensuring lower long-term drift and better rejection of environmental interference in demanding high-accuracy applications.
