Digital Barometric Pressure Sensor BMP388/BMP390 with I2C/SPI Interface, ±0.03 hPa High Accuracy, Low Power for Drones, Weather Stations, Mobile Devices, and Industrial IoT(BMP388)

Digital Barometric Pressure Sensor BMP388/BMP390 with I2C/SPI Interface, ±0.03 hPa High Accuracy, Low Power for Drones, Weather Stations, Mobile Devices, and Industrial IoT(BMP388)

• 【Low Power & Efficient】: BMP388 operates at ultra-low 3.4μA current during measurements and just 2.0μA in sleep mode, perfect for battery-powered IoT devices, drones, and portable weather stations requiring extended operational time without frequent recharging or battery replacement.
• 【High Precision Measurement】: BMP390 delivers exceptional ±0.03hPa relative accuracy (equivalent to 25cm altitude resolution) within 700-1100hPa range, providing reliable barometric data for indoor positioning systems, altitude tracking in mobile devices, and precise atmospheric pressure monitoring applications.
• 【Wide Temperature Range & Communication Flexibility】: Both sensors function flawlessly from -40°C to +85°C, supporting I2C (up to 3.4MHz) and (3-wire/4-wire, up to 10MHz) interfaces for seamless integration into, Pi, or custom PCB designs across automation and environmental monitoring projects.
• 【Dual Sensor Package with Complete Specifications】: Includes BMP388 (1.7-3.6V, 300-1250hPa range) and BMP390 (3.3-5V, I2C address 0x77/0x76 selectable) digital pressure sensors with pin headers, offering developers versatile options for prototyping weather forecasting systems, altitude measurement tools, or HVAC control applications.
• 【Fast Response & Long-Term Stability】: Features 2-millisecond startup time with ±0.16hPa/year stability and minimal ±0.6Pa/K temperature drift (@900hPa), insuring consistent performance for IoT sensors, smart home barometers, and outdoor activity trackers that demand accurate atmospheric data over extended deployment periods.
