BMP384 in Bosch BME280 / BMP280 Family
The BMP384 is a high-performance absolute barometric pressure sensor from Bosch Sensortec, specifically engineered for high precision and robustness in demanding environments. Building on the heritage of the BMP280, it features a gel-filled cavity that provides enhanced resistance to liquids and dust. This 24-bit digital sensor offers industry-leading temperature stability and low noise, making it ideal for applications requiring accurate altitude tracking and vertical velocity detection in compact, battery-powered electronic devices.
Variants in This Sub-Family
Variants within the BMP3xx series primarily differ based on their target application environments and package sealing. While the standard BMP388 targets mobile devices with a dry cavity, the BMP384 utilizes a specialized liquid-resistant gel. Other variants may offer different I2C/SPI interface configurations or factory calibration offsets tailored for specific pressure ranges, though the core 24-bit sensing architecture remains consistent across the high-performance family.
