Product Description

Product Introduction:

CJMCU-388BMP388 digital pressure sensor is a very small low power and low noise 24-bit sensor. This absolute pressure sensor is based on a mature sensing principle for pressure and temperature measurement. The BMP388 sensor has excellent design flexibility and is specifically designed for a variety of altitude tracking applications. The sensor has a best-in-class temperature coefficient offset (TCO) between 0°C and 65°C, which can be used for accurate altitude 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.
