BMP388 Barometric Pressure Sensor User Manual1 / 7BMP388 Barometric Pressure SensorUser ManualOVERVIEWThis is a 24-bit high precision barometric pressure sensor, which allows accuratealtitude tracing, as well as barometric pressure / temperature measuring. It supportsboth I2C and SPI interfaces, also is compatible with 3.3V/5V voltage levels.Due to its ultra-small form factor, low power consumption, low noise and highprecision, the BMP388 Barometric Pressure Sensor is suited for applications such asdrones, accurate altimeter, environment monitoring, and IoT projects, and so on.FEATURES⚫ Supports I2C (default) / SPI interface⚫ Onboard voltage level translator, compatible with 3.3V/5V operating voltage⚫ Comes with development resources and manual (examples for RaspberryPi/Arduino/STM32)SPECIFICATION⚫ Operating voltage: 3.3V/5V⚫ Communication interface: I2C/SPI⚫ Barometric pressure operation range: 300~1250hPa⚫ Barometric pressure absolute accuracy: ±0.40hPa (@900~1100hPa, 25~40℃)⚫ Barometric pressure relative accuracy: ±0.08hPa (@900~1100hPa, 25~40℃)⚫ Temperature coefficient offset: ±0.75Pa/K (@700~1100hPa, -20~65℃)）
