Atmospheric pressure sensor, capable of measuring up to 4060 hPa, which allows it to be used even in underwater projects to a depth of about 40 meters. Thanks to high precision (±0.5 hPa) and a sampling rate of up to 200 Hz, it is also ideal for dynamic measurements of altitude and pressure in atmospheric conditions. The built-in metal port allows remote pressure measurement through a tube, and compatibility with the STEMMA QT system and ready-made libraries for Arduino and CircuitPython make integration with microcontrollers quick and easy.
