{"title":"Adafruit LPS35HW Water Resistant Pressure Sensor","handle":"adafruit-lps35hw-water-resistant-pressure-sensor","url":"/products/adafruit-lps35hw-water-resistant-pressure-sensor","description":"The Adafruit LPS35HW is a water-resistant barometric pressure and temperature sensor from ST. The sensing element is housed in a ceramic package with waterproof gel protection, making it safe to use in damp and humid environments like outdoor weather stations.\n\nWith 24-bit pressure data and 16-bit temperature readings, the LPS35HW delivers ±0.1% hPa accuracy across a 260–1260 hPa range. Unlike the ported LPS33HW variant, this non-ported model is designed for general wet-environment use. It can withstand up to 20× its measurement range and features adjustable data rates with a built-in low-pass filter for clean readings.\n\nKey Features\n\n\nWater Resistant Sensor – Ceramic package with waterproof gel for use in damp and humid conditions\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\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 for easy wiring; SPI supported in Arduino\n\n3.3 V and 5 V Compatible – Onboard voltage regulator and level shifting\n\n\nIdeal For\n\nOutdoor weather stations in wet or humid conditions\nBarometric pressure and altitude monitoring\nHigh-humidity environmental sensing\nIoT sensor nodes exposed to moisture\n\n\nPackage Contents\n\n1× Adafruit LPS35HW Water Resistant Pressure Sensor Breakout\n1× Strip of header pins\n\n\n\nWarning: The sensor element itself is water 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\nLPS35HW Guide – Arduino & CircuitPython\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5158,"title":"Default Title","sku":"AF-4258","price":25.13,"on_sale":false,"in_stock":true,"available_quantity":64,"option1":"Default Title"}]}
