The sensing element is housed in a ceramic package with waterproof gel protection, making it suitable for long-term exposure to water, chlorine, bromine, commercial detergents, fuels, solvents, and other chemicals.\n\nWith 24-bit pressure data and 16-bit temperature readings, the LPS33HW delivers ±0.1% hPa accuracy across a 260–1260 hPa range (capable of withstanding up to 20× its measurement range). The ported sensor design includes a metal port with a lip for O-ring installation, allowing sealed pressure measurement setups.\n\nKey Features\n\n\nWater & Chemical Resistant – Ceramic package with waterproof gel, proven against chlorine, fuels, solvents, and detergents\n\n24-Bit Pressure Data – ±0.1% hPa accuracy from 260 to 1260 hPa\n\n16-Bit Temperature Data – Onboard temperature compensation for stable readings\n\nPorted Sensor Design – Metal port with lip for O-ring installation\n\nAdjustable Data Rate & Low-Pass Filter – Tune measurement speed and remove signal noise\n\nPressure Tolerance – Withstands up to 20× the measurement range\n\nI2C and SPI – I2C via STEMMA QT/Qwiic connectors; SPI supported in Arduino\n\n3.3 V and 5 V Compatible – Onboard voltage regulator and level shifting\n\n\nIdeal For\n\nWet or chemically harsh environments\nSealed pressure measurement systems with O-ring and tubing\nWeather stations and barometric monitoring\nIndustrial and scientific pressure sensing\n\n\nPackage Contents\n\n1× Adafruit LPS33HW Water Resistant Pressure Sensor Breakout (STEMMA QT)\n\n\n\nWarning: The sensor element itself is water/chemical resistant, but the breakout PCB is not. For wet environments, you must seal the rest of the board in waterproof epoxy.\n\n\nResources\n\nLPS33HW/LPS35HW Guide – Arduino & CircuitPython\nWhat is STEMMA QT?\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4514,"title":"Default Title","sku":"AF-4414","price":25.18,"on_sale":false,"in_stock":true,"available_quantity":58,"option1":"Default Title"}]}
