The BMP581 Pressure Sensor features a wide pressure-sensing range of 30 to125 kPa and maintains excellent accuracy across this range. It also supports output data rates up to 622Hz. The sensor comes with a configurable oversampling setting, a FIFO buffer for storing up to 32 pressure samples, programmable low-pass filtering, and 6-bytes of user-programmable non-volatile memory. This allows customization of the sensor performance based on the requirements of your application. The BMP581 Pressure Sensor operates over I2C, making it easy to connect to your project without any need for soldering.
With five operating modes - Normal, Forced, Continuous, Standby, and Deep Standby - the sensor offers flexibility in usage. Deep Standby mode consumes the least amount of current, making it an energy-efficient choice. Please note that the term "Micro Pressure Sensor" refers to the size of the board and not its sensing precision capabilities.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables designed to make prototyping faster and less error-prone. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space and ensures error-free connections.
The Qwiic Micro is the smallest I2C-supported board form-factor yet, measuring only 19.05mm by 7.62mm. It's 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.
Some of the key features of the SparkFun Qwiic BMP581 Pressure Sensor include a supply voltage range of 1.65V - 3.6V, a maximum current draw of 260µA during measurements, an absolute pressure accuracy of ±0.5hPa, a temperature sensing range of -40 - 85 °C, and a default I2C Address of 0x47.
