The BMP585 is a next-generation high-precision barometric pressure and temperature sensor from Bosch Sensortec, designed for accurate altitude and environmental measurements. It is an upgrade over earlier BMP series sensors (BMP280, BMP388, BMP390) and offers improved resolution, low noise performance, and fast conversion time.
This version features a ported pressure inlet, allowing a tube to be attached for remote or sealed pressure measurements. The sensor supports both I2C and SPI communication, making it suitable for a wide range of embedded systems, drones, wearables, and industrial applications.
The module includes onboard voltage regulation and logic level shifting, allowing safe operation with 3.3V or 5V microcontrollers. It is equipped with STEMMA QT / Qwiic connectors for solder-free, plug-and-play connections.
