Build with BMP388 — Datasheet Specs & AI Design Help

00 — Overview

What the BMP388 does

The BMP388 is a digital pressure and temperature sensor housed in a compact 10-pin metal-lid LGA package measuring 2.0 × 2.0 mm². It operates on a main supply voltage of 1.65 V to 3.6 V and consumes only 3.4 µA at 1 Hz. The device features a relative accuracy of typ. ± 8 Pa and supports digital interfaces up to 10 MHz. Engineers typically use it for vertical velocity indication, indoor navigation, weather forecasting, and health care applications like spirometry. Its low power consumption makes it ideal for battery-driven devices such as mobile phones, GPS modules, watches, and drones. The sensor enables accurate altitude tracking and supports data fusion for fitness and navigation systems.
