Adafruit LPS33HW Water Resistant Pressure Sensor - STEMMA QT
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)
