## Description

Built around the Bosch BMP585 chip, this Gravity module measures barometric pressure and temperature for altitude, weather and environmental sensing projects. Its gel-filled cavity and industrial protective cover help it resist water, moisture and chemical exposure, making it better suited to demanding outdoor or industrial builds than a bare MEMS sensor.The sensor delivers ±0.3 hPa typical absolute pressure accuracy, ±0.06 hPa / 10 kPa typical relative pressure accuracy and ultra-low noise below 0.1 Pa RMS. That level of sensitivity can support centimetre-level altitude change detection for uses such as drone altitude stabilisation, indoor floor detection, precision navigation and rugged weather monitoring.Integration is straightforward with both I2C and UART interfaces, a wide DC 3.3~5V operating range, Gravity PH2.0-4P connector and 2.54 mm pin header socket. The module is designed for use with platforms such as ESP32, Raspberry Pi and Arduino, and open-source code libraries are provided by the manufacturer.Included in the pack are the Gravity BMP585 sensor module, one PH2.0-4P sensor connection cable and one 10pin-2.54 black single row pin header.Features:Bosch BMP585 chip: high-precision digital barometric pressure and temperature sensing.Liquid-proof design: gel-filled cavity and industrial-grade protective cover resist water, humidity and corrosive elements.High accuracy: ±0.3 hPa absolute pressure accuracy and ±0.06 hPa relative accuracy.Ultra-low noise: below 0.1 Pa RMS without a low-pass filter enabled.Low power: approximately 700μA operating current for efficient environmental sensing.Flexible interfaces: supports both I2C and UART communication protocols.On-chip buffering: FIFO buffer reduces host microcontroller polling frequency.Built-in filtering: configurable IIR filter helps smooth data jitter from airflow and disturbances.Wide compatibility: works with 3.3V and 5V logic platforms such as ESP32, Raspberry Pi and Arduino.Open-source support: manufacturer-provided code libraries help speed up development.Specifications:Operating Voltage: DC 3.3~5VOperating Current: 700μACommunication Interface: I2C / UARTInterface Form: PH2.0-4P (Gravity Pinout) / 2.54mm Pin Header SocketI2C Address: 0x47 (Default) / 0x46Pressure Measurement Range: 30 ~ 125 kPaTemperature Measurement Range: 0 ~ 65 °CAbsolute Pressure Accuracy: ±0.3 hPa (Typ.)Relative Pressure Accuracy: ±0.06 hPa / 10 kPa (Typ.)Relative Altitude Accuracy: ±0.5 m / 10 kPaTemperature Drift Coefficient: ±0.5 Pa / KPressure Data Resolution: 1 / 64Ultra-Low Noise: < 0.1 Pa (RMS, without low-pass filter enabled)PCB Dimensions: 32 × 27 × 7.18 mmMounting Hole Spacing: 25 × 20 mmMounting Hole Diameter: 3.0 mmA strong choice for UAVs and drones, outdoor weather stations, sport altimeters, IoT floor detection, asset tracking and smart home HVAC airflow monitoring.
