Adafruit BMP581 I2C or SPI Temperature and Pressure Sensor

The Adafruit BMP58x Precision Barometric Pressure and Altimeter Breakout is at the forefront of sensor technology, offering unrivaled precision that surpasses its predecessors. Designed for both environmental sensing and precision altimetry, it operates seamlessly in either I2C or SPI modes, ensuring flexible connectivity and integration with various microcontrollers.

Specifications include an exceptional altitude noise level of only 1cm (0.08Pa) and a fast conversion time, which are critical for stability in dynamic applications such as drones. The sensor features a remarkable relative accuracy of ±0.4 Pascals at 900-1100 hPa and 25°C, equating to a mere ±3.3 centimeters altitude variance. The typical absolute accuracy stands at ±30Pa, about 2.5 meters, subject to changes based on environmental conditions.

Advanced enhancements also enable temperature measurement with a precision of ±0.5°C. The board is equipped with a 3.3V regulator and level shifters, making it compatible with both 3V and 5V logic microcontrollers. Configured in the STEMMA QT form factor, it ensures easy solderless connectivity through SparkFun Qwiic compatible I2C connectors.

Designed with projects like wearables and altimeter tracking in mind, this sensor delivers exceptional performance even in high-demand applications. Pair it with the accompanying Arduino library to retrieve data efficiently and embark on new explorations with outstanding precision.
