BMP581 I2C or SPI Temperature and Pressure for Adafruit - STEMMA QT Beskrivelse

BMP581 is a capacitive digital barometric sensor specifically designed for high-performance applications. It boasts excellent accuracy and ultra-low power consumption. This sensor utilizes advanced MEMS technology, providing reliable pressure and altitude measurement solutions for wearable devices, the Internet of Things, and mobile applications.
By pairing with the BMP581 evaluation board (not included), developers can quickly evaluate and integrate the various functions of the BMP58x series sensors, significantly shortening the product development cycle.
Wide measurement range: from 300 hPa to 1250 hPa, covering various application requirements
Ultra-high precision: absolute accuracy 30 Pa, relative accuracy 0.06 hPa (equivalent to 0.5 meters of altitude difference)
Low noise performance: RMS noise is only 0.08 Pa, ensuring data stability

Feature
Temperature stability: temperature coefficient offset (TCO) is only 0.5 Pa/K, reducing the impact of temperature changes measurements
Ultra-low operating power consumption: At an output data rate of 1Hz, the typical current consumption is only 1.3μA.
Deep sleep mode: The standby current is as low as 0.5μA, significantly extending battery life.
Intelligent power management: Supports multiple power consumption modes to meet the efficiency requirements of different application scenarios.
Built-in FIFO buffer: 512-byte storage space, preventing data loss in non-real- systems
Programmable IIR filter: Filter coefficients can be adjusted from 0 to 127, effectively suppressing short-term disturbances (such as pressure fluctuations caused by door opening and closing)
Flexible digital interface: Supports I2C ( to 2.5 MHz), SPI ( to 12 MHz), and I3C ( to 2.5 MHz) communication protocols
