SparkFun Pressure Sensor - BMP581 (Qwiic)

Description SparkFun BMP581 Pressure Sensor (Qwiic) Exceptional resolution with 1/64Pa pressure data On-chip linearization and temperature compensation Easy-to-use Qwiic Connect System for I2C communication Versatile SPI communication option available Wide pressure sensing range of 30 - 125 kPa The SparkFun BMP581 Pressure Sensor (Qwiic) is a 1 by 1 inch absolute pressure sensor breakout from Bosch Sensortec. It offers exceptional resolution (down to 1/64 Pa) and accuracy, with on-chip linearization and temperature compensation for accurate pressure and temperature data. The sensor communicates via I2C using the Qwiic Connect System, eliminating the need for soldering. Additionally, I2C signals are routed to 0.1-inch spaced pins for those who prefer a soldered connection, and the board can be configured for SPI communication using the same pins.
