7Semi BMP581 High-Precision Barometric Pressure & Altitude Sensor Breakout

The 7Semi BMP581 Barometric Pressure & Altitude Sensor Breakout is engineered for projects that demand highly accurate atmospheric pressure and altitude data. Built on Bosch’s advanced sensing technology, this compact module delivers exceptional precision with ±30 Pa absolute accuracy and ±6 Pa relative accuracy, translating to altitude precision as fine as ±0.5 meters. Its ability to operate across a wide 300–1250 hPa pressure range makes it ideal for applications like weather stations, environmental monitoring, and UAV altitude tracking.

Designed for effortless integration, the BMP581 supports I2C, I3C, and SPI interfaces, making it compatible with a wide range of development boards and embedded systems. The Qwiic connector ensures solder-free wiring, while the low-power operation makes it suitable for portable and battery-powered devices.

Whether you’re building an IoT sensor node, a smart altimeter, or barometric logging system, this breakout brings reliable performance, high sensitivity, and fast data rates, perfect for altitude measurement and barometric pressure sensing projects.
