The SparkFun Qwiic BMP581 Pressure Sensor is a micro-sized, absolute pressure sensor breakout from Bosch Sensortec. The BMP581 boasts exceptional resolution and accuracy (down to 1/64Pa) and uses on-chip linearization and temperature compensation to provide true absolute data for pressure and temperature. This version of the BMP581 Pressure Sensor is in the smallest Qwiic form-factor yet, the Qwiic Micro. These breakouts measure just 0.75in. by 0.30in. to make it so you can install these sensors in projects with exceptionally tight spaces.

The BMP581 has a wide pressure-sensing range (30 to125 kPa) 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 low-pass filtering, the BMP581 has very low noise (< 0.1Pa RMS). The Qwiic Micro Pressure Sensor communicates over I2C, utilizing our handy Qwiic Connect System, so no soldering is required to connect it to the rest of your project. Sorry SPI users, there is no space on this Micro-sized breakout for any extra pins for that communication protocol. If you prefer a soldered connection or SPI, the Standard Qwiic version of this board features those options.

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.

Note: Although this board is called "SparkFun Micro Pressure Sensor," the name only refers to the size of the board and not its sensing precision capabilities. If you are looking for a "MicroPressure" sensor calibrated to sensing pressure ranges of 1-25psi from liquid media, check out the SparkFun Qwiic MicroPressure Sensor instead!

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.

Qwiic Micro is our smallest I2C-supported board form-factor yet! At only 0.75in. by 0.30in. (or 24.65mm by 7.62mm for metric friends), Qwiic Micro is perfect for projects and applications that have space or weight concerns. With just a single Qwiic connector, Micro boards work great alongside the Qwiic Multiport or at the end of a Qwiic daisy chain.
