The module is equipped with the BMP384 system, which measures the atmospheric pressure in a wide range from 300 hPa to 1250 hPa and temperature in the range from -40 °C to 85 °C. The sensor has a high measurement resolution - up to 24 bits, and has additional protection for the system against moisture. There are two Qwiic connectors on the board, which facilitate the prototyping process. SparkFun Pressure Sensor has a configurable oversampling setting, a FIFO buffer for storing up to 73 measurements and a built-in low-pass filter, thanks to which users can adjust the sensor's performance to the requirements of the application.
