It measures pressure and temperature with high precision, offering ±0.3 hPa typical absolute pressure accuracy for detecting small altitude, floor-level or liquid-level changes.The module supports I2C, I3C and SPI, making it suitable for a wide range of microcontrollers and embedded systems. Its 2.54 mm pin header socket helps with breadboarding and integration into finished PCBs, while the onboard BMP581 features digital filtering and a hardware FIFO buffer for smoother data output.With low operating current and a 2 μA sleep current, it is well suited to battery-powered IoT nodes, wearables and compact sensing projects. The product wiki provides a connection diagram, library, schematic, dimensions and component layout diagram, CAD files and the BMP581 chip datasheet.The package includes the Fermion: BMP581 High-Precision Barometric Pressure & Temperature Sensor ×1 and a 10pin-2.54 Black Single Row Pin Header ×1.Specifications:Operating Voltage: DC 3.3VOperating Current: 200μASleep Current: 2μACommunication Interface: I2C / I3C /SPIInterface Form: 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: 19×16×2.49 mmMounting Hole Spacing: 14 mmMounting Hole Diameter: 2.0 mmLogic note: This module operates at 3.3V logic. A logic level converter is required when using with 5V microcontrollers (e.g., Arduino Uno).Ideal applications include drone stability hovering and vertical velocity control, GPS navigation enhancement, indoor navigation and floor localisation, fitness tracking, precision weather stations and hydrological monitoring.","vendor":"DFRobot","product_type":"Barometric Pressure Sensor","in_stock":true,"options":[],"variants":[{"id":15682,"title":"Default Title","sku":"DF-SEN0667","mpn":"SEN0667","price":14.08,"on_sale":false,"in_stock":true,"available_quantity":209}]}
