{"product_id":"adafruit-lps33hw-water-resistant-pressure-sensor-stemma-qt","title":"Adafruit LPS33HW Water Resistant Pressure Sensor","description":"\u003cp\u003eSometimes you need to sense pressure in a damp or caustic environment. And sometimes you need to know the relative changes in pressure as well as the absolute pressure. For the times you need to do both (or either), the LPS33HW is the pressure sensor for you.\u003c\/p\u003e\n\u003cp\u003eCombining protection from water intrusion with support for high precision relative and absolute measurements, this sensor will do what you need. With drivers for CircuitPython, Arduino, and Raspberry Pi, and support for I2C or SPI (Arduino only SPI support, for now) you'll be measuring pressure in any situation in no time.\u003c\/p\u003e\n\u003cp\u003eAccording to ST, the LPS33HW is designed for and proven to protect electronic components from long-term exposure to harsh environments such as water mixed with chlorine, bromine, commercial washing detergent and fuels, solvents and chemicals. The sensing element is nestled safely in a ceramic package and is encased in a waterproof gel that prevents water that gets into the sensor from interfering with readings.\u003cbr\u003e\u003cbr\u003eThe LPS33HW has a 24bit pressure data and 16 bit temperature data, allowing it to deliver pressure readings with +\/- 0.1% hPa accuracy. It can measure from 260 to 1260 hPa and is able to withstand pressure up to 20 times its measurement range. To help you take measurements to your requirements, the LPS33HW also offers an adjustable data rate, as well as a low pass filter to remove noise from the signal. Finally, the onboard temperature compensation makes sure that your readings are always good and won't vary as the temperature changes.\u003c\/p\u003e\n\u003cp\u003eThis sensor has a metal port with a lip that can be used to install an O-ring.

Additionally since it speaks I2C you can easily connect it up with two wires (plus power and ground!).  They've even included \u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSparkFun qwiic\u003c\/a\u003e compatible\u003cstrong\u003e \u003ca target=\"_blank\" rel=\"noopener noreferrer\" href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\"\u003eSTEMMA QT\u003c\/a\u003e\u003c\/strong\u003e connectors for the I2C bus so \u003cstrong\u003eyou don't even need to solder!\u003c\/strong\u003e Just wire up to your favorite micro and you can use our CircuitPython\/Python or Arduino drivers to easily interface with the LPS33ASAP.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease Note: The sensor itself is advertised as Water\/Chemical Resistant, but the breakout board for testing out this sensor is not!
