BMP388 High Precision Barometric Pressure Sensor

Overview

The BMP388 is a sophisticated 24-bit barometric pressure sensor designed for precise altitude tracking and accurate measurements of barometric pressure and temperature. It features dual communication interfaces—I2C and SPI—and operates seamlessly at both 3.3V and 5V voltage levels.

Key Features

• Dual Interface Support: Compatible with I2C (default) and SPI communication protocols.
• Voltage Compatibility: Equipped with an onboard voltage level translator, making it suitable for both 3.3V and 5V systems.
• Comprehensive Development Resources: Includes manuals and examples tailored for popular platforms such as Raspberry Pi, Arduino, and STM32.

Technical Specifications

• Operating Voltage: Supports both 3.3V/5V power supply.
• Communication Protocols: I2C/SPI interface options available.
• Pressure Measurement Range: Operates within a range of 300 to 1250 hPa.
• Absolute Accuracy in Pressure Measurement: ±0.40 hPa (at pressures between 900 to 1100 hPa within the temperature range of 25 to 40 degrees Celsius).
• Relative Accuracy in Pressure Measurement: ±0.08 hPa (at similar conditions).
• Temperature Coefficient Offset: ±0.75 Pa/K (within the range of -20 to +65 degrees Celsius).
• Temperature Accuracy: ±0.5 degrees Celsius (from temperatures ranging from 0 to +65 degrees Celsius).
• Resolution Capability: Achieves a resolution of up to 0.016 Pa in high precision mode.
• Sampling Rate Potential: Capable of sampling at rates up to 200 Hz.
• Operating Temperature Range: Functions effectively between -40°C to +85°C.
