A miniature sensor equipped with the BMP581 system by Bosch Sensortec enables the measurement of atmospheric pressure in the range from 30 hPa to 125 kPa with an accuracy of ± 0.5 hPa and temperature in the range from -40 °C to 85 °C. The sensor has a very high measurement resolution, reaching up to 1/64 Pa. It features a configurable oversampling setting, a FIFO buffer to hold up to 32 pressure samples, programmable low-pass filtering, and up to 6 bytes of user-programmable non-volatile memory.
