{"title":"Fermion: BMP390L Digital Barometric Pressure Sensor (Breakout)","handle":"fermion-bmp390l-digital-barometric-pressure-sensor-breakout","url":"/products/fermion-bmp390l-digital-barometric-pressure-sensor-breakout","description":"A high-precision digital barometric pressure sensor breakout based on the Bosch BMP390L. Designed for industrial-grade applications, it delivers exceptional temperature stability, low drift, and ultra-low power consumption — making it ideal for indoor positioning, altitude tracking, and environmental monitoring where GPS signals may not be available.\n\nWith an absolute accuracy deviation of less than 50 Pa and relative accuracy of ±3 Pa (equivalent to approximately 25 cm altitude), the BMP390L significantly outperforms its predecessors. Long-term stability drift of only ±16 Pa per year ensures reliable readings over extended deployments. Extended availability is guaranteed up to 10 years.\n\nKey Features\n\n\nHigh Precision – Absolute accuracy <50 Pa, relative accuracy ±3 Pa (~25 cm altitude)\n\nExcellent Long-Term Stability – ±16 Pa/year drift\n\nUltra-Low Power – 54 µA sleep, 357–650 µA in measurement mode\n\nLow Noise – Less than 0.02 Pa noise impact\n\nDual Interface – I2C and SPI communication\n\nSelectable I2C Address – 0x77 (default) or 0x76 (SDO to GND)\n\n\nSpecifications\n\n\nOperating Voltage – 3.3 V\n\nPressure Range – 300–1250 hPa\n\nRelative Accuracy – ±0.03 hPa (700–1100 hPa, 25–40°C)\n\nAbsolute Accuracy – ±0.50 hPa\n\nTemperature Coefficient – ±0.6 Pa/K (900 hPa, 25–40°C)\n\nStart-Up Time – 2 ms\n\nOperating Temperature – −40°C to +85°C (full precision 0–65°C)\n\nDimensions – 15 × 20 mm\n\n\nIdeal For\n\nIndoor positioning and floor detection\nDrone flight stabilisation and altitude hold\nWater level measurement\nGPS navigation enhancement\nHealth care (spirometry)\nAR/VR applications\n\n\nPackage Contents\n\n1× BMP390L barometric pressure sensor breakout\n1× 2.54 mm 7-pin header\n1× 2.54 mm 4-pin header\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2630,"title":"Default Title","sku":"DF-SEN0423","price":18.47,"on_sale":false,"in_stock":true,"available_quantity":63,"option1":"Default Title"}]}
