## Description

The Adafruit LPS33HW is a water-resistant barometric pressure sensor designed for use in harsh environments. 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. With 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. Key Features Water & Chemical Resistant – Ceramic package with waterproof gel, proven against chlorine, fuels, solvents, and detergents 24-Bit Pressure Data – ±0.1% hPa accuracy from 260 to 1260 hPa 16-Bit Temperature Data – Onboard temperature compensation for stable readings Ported Sensor Design – Metal port with lip for O-ring installation Adjustable Data Rate & Low-Pass Filter – Tune measurement speed and remove signal noise Pressure Tolerance – Withstands up to 20× the measurement range I2C and SPI – I2C via STEMMA QT/Qwiic connectors; SPI supported in Arduino 3.3 V and 5 V Compatible – Onboard voltage regulator and level shifting Ideal For Wet or chemically harsh environments Sealed pressure measurement systems with O-ring and tubing Weather stations and barometric monitoring Industrial and scientific pressure sensing Package Contents 1× Adafruit LPS33HW Water Resistant Pressure Sensor Breakout (STEMMA QT) Warning: 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. Resources LPS33HW/LPS35HW Guide – Arduino & CircuitPython What is STEMMA QT?
