Bosch BMP581 Barometric Pressure Sensor

High performance, small footprint, and accurate

The Bosch BMP581 Barometric Pressure Sensor is the new benchmark in the field of barometric pressure sensors and impresses with its enormous accuracy. This enables endless and new use cases such as fitness tracking where accurate altitude change is key.

The low power and low noise 24-bit BMP581 absolute barometric pressure sensor significantly improved its accuracy compared to previous generations at the smallest size. The sensor also provides true absolute pressure and temperature due to on-chip linearization and temperature compensation.

This Bosch pressure sensor offers outstanding design flexibility, providing a single package solution that customers can easily integrate into a multitude of existing and upcoming devices such as GPS modules, wearables, hearables, smart home, IoT and industrial products.
