SparkFun BMP581 Pressure Sensor (Qwiic) - I2C/SPI, 30-125kPa, ±0.5hPa Accuracy
The SparkFun BMP581 Pressure Sensor is a high-precision, low-power barometric pressure sensor from Bosch Sensortec, featuring a Qwiic connector for solderless I2C integration with Arduino, Raspberry Pi, and other 3.3V microcontrollers. It provides absolute pressure and temperature data with on-chip linearization and temperature compensation.
Features
- High-resolution absolute pressure sensing from 30 to 125 kPa with a resolution down to 1/64 Pa.
- Exceptional absolute pressure accuracy of ±0.5 hPa across the full operating temperature range.
- Dual communication interface: default Qwiic I2C (up to 1 MHz) and configurable SPI (up to 12 MHz) via breakout pins.
- Ultra-low power operation, drawing as low as 0.55 µA in deep standby mode and 1.3 µA at 1 Hz in low-power mode.
- Integrated features include a 32-sample FIFO buffer, configurable oversampling, and 6 bytes of non-volatile memory.

The BMP581 from Bosch Sensortec is a MEMS-based absolute pressure sensor designed for high-accuracy environmental monitoring and altitude tracking. It incorporates advanced signal conditioning, linearization, and temperature compensation algorithms on-chip to deliver stable, true absolute pressure data without requiring external processing.
Operating from a 1.71V to 3.6V supply, it is optimized for battery-powered applications. The sensor supports a wide output data rate from 0.125 Hz to 240 Hz in normal mode, with a burst rate up to 622 Hz in continuous mode, allowing for flexible power/performance trade-offs. Its robust design ensures reliable operation from -40°C to +85°C.
