Use it for weather monitoring, altitude estimation, or any project where accurate air pressure readings are needed.\n\nThe LPS25 delivers 24-bit pressure measurements at up to 25 Hz, with accuracy within 0.2 hPa after calibration. This STEMMA QT breakout includes level shifting and voltage regulation, making it compatible with both 3.3 V and 5 V systems. Connect via solderless STEMMA QT/Qwiic cables or solder to the standard header pins for breadboard use.\n\nKey Features\n\n\nWide Pressure Range – 260 to 1260 hPa absolute pressure measurement\n\n24-Bit Resolution – High-precision pressure data at up to 25 Hz\n\n±0.2 hPa Accuracy – After calibration (±1 hPa before calibration)\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 libraries with example code\n\n\nIdeal For\n\nWeather stations and barometric pressure monitoring\nAltitude estimation and indoor navigation\nEnvironmental sensing and data logging\nIoT sensor nodes and portable instruments\n\n\nPackage Contents\n\n1× Adafruit LPS25 Pressure Sensor Breakout (STEMMA QT)\n\n\n\nNote: STEMMA QT cable not included — available separately.\n\n\nResources\n\nLPS25 Pressure Sensor Guide – Arduino & CircuitPython\nWhat is STEMMA QT?\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2962,"title":"Default Title","sku":"AF-4530","price":20.02,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
