BMP581 High-Performance Pressure Sensor

Bosch Sensortec’s BMP581 is characterized by its very small size, low-power consumption, and low-noise

Image of Bosch Sensortec's BMP581 High-Performance Pressure SensorBosch Sensortec’s BMP581 barometric pressure sensor features a wide 300 hPa to 1250 hPa measurement range and absolute accuracy of ±30 Pa. The BMP581 is designed for high-performance applications like fitness measurements with ±6 Pa. This is equivalent to a ±50 cm difference in altitude and an offset temperature coefficient (TCO) of 0.5 Pa/K. The device's low power consumption and integrated 512 byte FIFO buffer supports low-power applications and prevents data loss in non-real-time systems. The BMP581 is equipped with a built-in IIR filter to minimize short-term disturbances in the output data (for example, the slamming of a door or a window). The filter coefficient ranges from 0 (off) to 127.
