Description

BMP384 is a MEMS barometric pressure sensor designed to measure atmospheric pressure (and temperature) for altitude estimation and context-aware sensing. It integrates a calibrated pressure sensor with a digital interface and outputs compensated pressure and temperature data over I2C or SPI. It typically offers low active current, low sleep current, and a wide operating temperature range, suitable for mobile devices, drones, and wearables. Typical workflow: power up, configure oversampling/filters, read compensated pressure and temperature, and compute altitude (or use precomputed altitude). Software libraries exist for many platforms (Arduino, Raspberry Pi, etc.), along with Bosch’s sensor drivers. Key strengths: small footprint, low power, good long-term stability. If you have a specific package, supply voltage, or data-rate requirement, share the datasheet revision and I’ll tailor the summary and example code.
