Description

This is a newly-introduced Breakout version of the BMP388 Sensor from DFRobot with pressure and temperature measurement. It supports Arduino code control and offers lower power consumption, smaller size, higher resolution and sampling rate compared with its predecessors the BMP180 and BMP280.

Barometric sensors are usually used to measure barometric pressure and temperature. But besides that, they can also measure altitude and relative floor height due to the fact that there is a certain relationship between altitude and barometric pressure. Moreover, BMP388 enables accurate altitude tracking and is specifically suited for drone applications.

Based on Bosch’s proven piezo-resistive pressure sensor technology, BMP388 features high EMC robustness, high accuracy, and low power. It offers an accuracy of ±8Pa, which is equivalent to about ±0.66m difference in altitude, and an absolute accuracy temperature of ±0.5℃ for a temperature range between 0℃ and 65℃.
