A capable sensor

The ST LPS35HW is a water resistant barometric pressure and temperature sensor that is also safe to use in wet

environments. 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. It does not carry any ratings for resistance to

moisture so you probably don't want to take it to the bottom of the Mariana Trench, but it should work well for normal

wet situations like weather stations or high humidity.

Along with not being afraid of getting wet, the LPS35HW 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 LPS35HW 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.
