概述

Description

BMP384 is a digital barometric pressure sensor from Bosch Sensortec (BMP family). It measures ambient pressure and temperature using a MEMS sensor and communicates over I2C or SPI, typically from a 1.8–3.6 V supply. The device stores factory calibration data in non‑volatile memory; you read these coefficients once and use them to compensate raw readings. Output is pressure in pascals and temperature in degrees Celsius, with altitude computable from pressure using the standard atmosphere. It supports configurable oversampling and digital filtering to balance speed and noise. Common uses include altimeters for drones and wearables, weather monitoring, and indoor navigation. Basic workflow: initialize, read calibration data, configure oversampling/filter, trigger readings, apply compensation, and convert to hPa or meters of altitude.

Features

- Bosch Sensortec digital barometer
- Measures barometric pressure and temperature; outputs digital data
- Interfaces: I2C and SPI
- Fully calibrated and temperature-compensated on-chip (coefficients stored in device)
- 24-bit ADC for pressure (and temp) data with internal filtering
- Low power with multiple modes: single-shot and continuous measurement
- Wide supply voltage: typically 1.7–3.6 V
- Operating temperature range generally around -40 to +85 °C
- Small package for compact applications (wearables, drones, IoT)
- No external calibration required; robust noise/offset compensation
- Suitable for altimeter, weather, and altitude-detection applications

Package

BMP384 is packaged in an 8-pin leadless LGA (DFN) package, typically with a 2.0 x 2.0 mm footprint.

Pinout

8 pins. It is a digital barometric pressure sensor (measures pressure and temperature) whose data is output over I2C or SPI. Pins provide power (VDD) and ground (GND), the interface lines (SDA/SCL for I2C or SCK/SDI/SDO/CS for SPI), and usually an optional interrupt/DRDY pin.

Manufacturer

- Manufacturer: Bosch Sensortec (a subsidiary of the Bosch Group, Robert Bosch GmbH)
- What kind of company: A German multinational engineering and electronics company that specializes in MEMS sensors for consumer devices.

Application

BMP384 is a digital barometric pressure sensor for accurate ambient-pressure measurement with low power. Typical applications include:
- Altitude and vertical-velocity estimation for drones/UAVs
- Indoor navigation and floor-level positioning
- Weather monitoring and meteorological stations
- Wearables and activity trackers tracking altitude changes
- IoT environmental sensing and smart-building automation
- Robotics/autonomous systems for terrain and pose estimation
- HVAC/industrial pressure monitoring

Equivalent

Equivalent or drop-in alternatives to BMP384 include:
- Bosch BMP388 (same BMP3xx family, newer generation)
- ST LPS22HB / LPS25H MEMS barometers (I2C/SPI)
- TE Connectivity / MEAS MS5803-01BA and MS5611 (24‑bit altimeters)
Note: pinouts, interfaces, ranges, and calibration differ; verify compatibility for your design.
