Use it for weather monitoring, altitude estimation, or any application where precise air pressure data matters.\n\nDespite its miniature 2×2 mm package, the LPS22 delivers 24-bit pressure measurements at up to 75 Hz, with accuracy within 0.1 hPa after one-point calibration. This STEMMA QT breakout adds level shifting and voltage regulation, making it compatible with both 3.3 V and 5 V systems — no soldering required with STEMMA QT/Qwiic cables.\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 75 Hz\n\n±0.1 hPa Accuracy – After one-point calibration (±1 hPa before calibration)\n\nUltra-Compact Sensor – 2×2 mm LPS22HB, one of the smallest pressure sensors available\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\nWearable devices and smartwatch projects\nEnvironmental sensing and data logging\n\n\nPackage Contents\n\n1× Adafruit LPS22 Pressure Sensor Breakout (STEMMA QT)\n\n\nResources\n\nLPS22/LPS25 Pressure Sensor Guide – Arduino & CircuitPython\nWhat is STEMMA QT?\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4120,"title":"Default Title","sku":"AF-4633","price":14.4,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
