Gravity BMP585 High Precision Air Pressure and Temperature Sensor I2C UART

The DFRobot Gravity SEN0664 is a high-precision digital air pressure and temperature sensor based on the Bosch BMP585 in a rugged industrial design. The special feature of the BMP585-Gravity module compared to its BMP581 counterpart (SEN0665) is the gel-like protection design ("Gel-Fill"), which secures the sensor against water, moisture, and chemical influences – making it suitable for outdoor applications and moisture-laden environments such as weather stations, outdoor UAVs, and hydrology.

Features:

• Bosch BMP585 with ±0.3 hPa absolute accuracy and < 0.1 Pa noise in a rugged Gel-Fill protective design for moisture-laden outdoor deployments
• Three-parameter output: air pressure (30–125 kPa), temperature, and calculated altitude with ±0.5 m relative altitude accuracy / 10 kPa
• Gel-Fill protection design against water, moisture, and chemical influences – higher durability compared to unprotected modules
• Configurable IIR filter and hardware FIFO buffer for noise-reduced, stable measurement data without host overloading
• Optional I2C or UART via DIP switch; setting remains after power interruption; operating voltage 3.3–5 V
• Low operating current ~700 µA for battery-powered outdoor sensors, UAVs, and sports equipment with long runtime

Application Examples:

• Outdoor UAV and drone systems with reliable altitude control despite moisture and temperature fluctuations
• Outdoor weather stations for air pressure, temperature, and altitude logging in exposed locations with moisture protection
• Hydrology monitoring: water level measurement based on air pressure in moisture-rich environments such as river measurement stations
• Sports altimeters for hiking, climbing, and cycling with Gel-Fill protection in rain and splashes
• Industrial environmental monitoring in humid production halls, greenhouses, and cooling systems
