The SparkFun Qwiic BMP581 Pressure Sensor is a standard-sized, 1in. by 1in. absolute pressure sensor breakout from Bosch Sensortec. The BMP581 boasts exceptional resolution (down to 1/64Pa) and accuracy while maintaining on-chip linearization and temperature compensation to provide true absolute data for pressure and temperature. The Qwiic Pressure Sensor communicates over I2C by default, utilizing our handy Qwiic Connect System so no soldering is required to connect it to the rest of your boards. However, we still routed the I2C signals out to a set of 0.1”-spaced pins for users who prefer a soldered connection. You can also configure the board to communicate over SPI using the same 0.1"-spaced pins.

The BMP581 has a wide pressure sensing range (30 to 125kPa) with excellent accuracy across the sensing range (± 0.5hPa (max)), as well as output data rates up to 622Hz (we have only regularly achieved 500Hz in testing, though). The sensor includes a configurable oversampling setting, FIFO buffer for storing up to 32 pressure samples, programmable low-pass filtering and even 6-bytes of user-programmable non-volatile memory. All of this allows you to customize the performance based on your application's requirements. Even without filtering, the BMP581 has very low noise (< 0.1Pa RMS).

The sensor has five operating modes: Normal, Forced, Continuous, Standby, and Deep Standby. Deep Standby consumes the least amount of current at just 1.5µA (typical) and peak current consumption by the sensor is 260µA.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
