DFRobot Gravity BMP581 Barometrischer Drucksensor I2C UART

The DFRobot Gravity BMP581 is a high-precision barometric pressure sensor based on the advanced Bosch BMP581. This sensor offers outstanding absolute accuracy of ±0.3 hPa and noise levels of less than 0.1 Pa, making it one of the best options in pressure sensing. With a pressure measurement range of 30 to 125 kPa and a relative altitude accuracy of ±0.5 m, the BMP581 is ideal for applications that require precise environmental data. The integrated IIR filtering and hardware FIFO buffer ensure stable measurement data by reducing data noise and relieving the host microcontroller. The sensor can communicate via I2C or UART, with configuration easily adjustable through a DIP switch. With a low operating current of about 700 µA, the BMP581 is particularly energy-efficient and is excellent for portable devices and battery-powered applications.

• High-precision pressure sensor with ±0.3 hPa accuracy
• Three-parameter output: pressure, temperature, and altitude
• Integrated IIR filtering for noise-reduced data
• Optional I2C or UART for flexible connectivity
• Low operating current of ~700 µA for efficiency.
