Introduction:

CJMCU-388 The BMP388 digital air pressure sensor is a very compact, low power and low noise 24-bit sensor.

This absolute air pressure sensor is based on proven sensing principles for pressure and temperature measurements.

The BMP388 sensor offers outstanding design flexibility and is specifically designed for a wide range of height tracking applications. The sensor offers a good temperature coefficient offset (TCO) between 0°C and 65°C for accurate height measurement over a wide temperature range.

The digital sensor has low power consumption of 3.4μA at 1Hz and a wide measurement range from 300hPa to 1250hPa.
