This makes it suitable for underwater depth sensing (up to ~40 metres) as well as standard altitude and weather monitoring.\n\nWith 24-bit resolution, ±0.5 hPa accuracy at the highest quality settings (less than 1 cm altitude resolution), and up to 200 samples per second, the LPS28 delivers exceptional precision and speed. The sensor includes a metal port for connecting thin tubing and features potting gel rated for up to 10,000 hPa with chemical resistance — check the datasheet for compatibility details.\n\nKey Features\n\n\nExtended Pressure Range – Measures from 260 to 4060 hPa (equivalent to ~40 m underwater)\n\n24-Bit Resolution – ±0.5 hPa accuracy at highest quality, less than 1 cm altitude precision\n\nUp to 200 Hz Sample Rate – Fast unfiltered readings for dynamic applications\n\nPorted Sensor Design – Metal port for connecting tubing to measure remote pressure sources\n\nChemical-Resistant Potting – Gel rated to 10,000 hPa with protection against harsh chemicals\n\nSTEMMA QT / Qwiic – Solderless I2C connectors for easy plug-and-play wiring\n\n3.3 V and 5 V Compatible – Onboard voltage regulator and level shifting\n\nArduino & CircuitPython Libraries – Ready-to-use drivers with example code\n\n\nIdeal For\n\nUnderwater depth sensing for ROVs and submersible robots\nHigh-precision altitude measurement\nWeather stations and barometric monitoring\nIndustrial pressure measurement via tubing\n\n\nPackage Contents\n\n1× Adafruit LPS28 (LPS28DFW) Pressure Sensor Breakout (STEMMA QT)\n\n\n\nNote: STEMMA QT cable not included — available separately. Check the datasheet to confirm chemical compatibility before exposing the sensor to specific liquids or gases.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":697,"title":"Default Title","sku":"AF-6067","mpn":"ADA6067","price":24.54,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":56,"option1":"Default Title"}]}
