Product Introduction

The BMP388 is a digital sensor with pressure and temperature measurement based on proven sensing principles. The sensormodule is housed in an extremely compact 10-pin metal-lid LGApackage with a footprint of only 2.0x 2.0 mm2 and max 0.8mm package height. Its smalldimensions and its low power consumption of 3.4 uA @1Hz allow the implementation in batterydriven devices such as mobile phones, GPS modules or watches.

Features

Best-in-class TCO between -20-65°C for accurate altitude measurement
Built-in hardware synchronization of pressure sensor data
New interrupt functionality: Data ready interrupt, watermark interrupt, FIFO full interrupt
Integrated 512 byte FIFO buffer

Applications

Vertical velocity indication (e.g. rise/sink speed)
Internet of things
Enhancement of GPS navigation (e.g. time-to-first-fix improvement, dead-reckoning, slope detection)
Indoor navigation & localization (floor detection, elevator detection)
Outdoor navigation, leisure and sports applications
Weather forecast
Health care applications (e.g. spirometry)
Fitness applications like enhancement of calorie detection
AR & VR applications
Context awareness
