Pressure Sensor - barometer - 300-1250hPa - BMP384 - Qwiic - SparkFun SEN-19662

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 an additional protection of the system against moisture - it is not fully waterproof, but can be used near water or in a humid environment. 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.

What is the atmospheric pressure? You will measure them with the SparkFun Pressure Sensor module.

A barometer is a pressure sensor that measures total air pressure. Atmospheric pressure depends on weather conditions and varies with altitude. Are you wondering what atmospheric pressure is good for a human being? The value of the atmospheric pressure, the so-called normal pressure is 1013.25 hPa and decreases with increasing altitude. Only heat above this value is considered high and dangerous.
