Product Description
Product Description
The DFRobot Gravity: BMP581 barometric pressure sensor module SEN0665 is a digital pressure and temperature sensing module based on the Bosch BMP581. The variant "Gravity: BMP581 Barometric Pressure Sensor (±0.3hPa High Accuracy, I2C / UART)" is intended for precise atmospheric pressure measurement and altitude-related calculations in compact embedded systems.
The module combines ±0.3 hPa absolute pressure accuracy with pressure noise below 0.1 Pa. With support for both I2C and UART and native compatibility with 3.3 V and 5 V systems, it can be integrated into microcontroller, robotics, and data logging platforms. According to the source, the board also provides features such as FIFO, an IIR filter, and non-volatile configuration storage for hardware-level signal conditioning and stable data acquisition.
