Description
Product information "SparkFun Qwiic BMP581"
The BMP581 has a wide pressure measurement range (30 to 125 kPa) with excellent accuracy over the entire measurement range (max. 0.5hPa) and an output data rate of up to 622Hz (in our tests, however, we only achieved 500Hz). The sensor has a configurable oversampling setting, a FIFO buffer for storing up to 32 pressure readings, programmable low-pass filtering and even a 6-byte user-programmable non-volatile memory. All this allows you to customise the performance to the requirements of your application. Even without low-pass filtering, the BMP581 has very low noise (< 0.1Pa RMS). The Qwiic Micro pressure sensor communicates via I2C and utilises our convenient Qwiic Connect system, so no soldering is required to connect it to the rest of your project. Unfortunately for SPI users, there is no room on this micro-sized breakout for additional pins for this communication protocol. If you prefer a soldered connection or SPI, the standard Qwiic version of this board offers these options.
The sensor has five operating modes: Normal, Forced, Continuous, Standby and Deep Standby. Deep Standby consumes the least amount of current at only 1.5µA (typical) and the peak current consumption of the sensor is 260µA.
Note: Although this board is called "SparkFun Micro Pressure Sensor", the name refers only to the size of the board and not to its measurement accuracy. If you are looking for a"MicroPressure" sensor that is calibrated for pressure ranges of 1-25psi of 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 error-prone. All Qwiic-enabled boards use a common 4-pin JST connector with 1 mm spacing. This means less space is required on the PCB and thanks to the polarised connectors you can't connect anything incorrectly.
QwiicMicro is our smallest I2C-supported board shape yet! Measuring just 0.75 x 0.30 inches (or 24.65 x 7.62 mm for metric friends), Qwiic Micro is perfect for projects and applications where space or weight is an issue. With just a single Qwiic connector, the Micro boards are ideal as an addition to the Qwiic Multiport or at the end of a Qwiic daisy chain.

Safety instructions
- Only operate the sensor with the specified operating voltage to avoid damage and danger.
- Avoid contact with water unless the product is expressly labelled as waterproof or watertight.
- Protect the sensor from mechanical impacts such as knocks or bumps.
- Do not open, modify or disassemble without authorisation, as this may impair the function and cause hazards.
- Connection should only be carried out by qualified personnel to prevent incorrect wiring.
- Ensure that the sensor is suitable for the measured pressure ranges to avoid overloading.
- Remove the sensor from the system if it is defective to prevent consequential damage.
- Disconnect the electrical connections before disposal and treat the device as electronic waste in accordance with the applicable disposal regulations.
- Properly recycle packaging materials to minimise environmental impact.
- Do not dispose of improperly, e.g. in household waste.
