Overview

Sometimes you need to sense pressure when it's wet. 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 LPS35HW is the pressure

sensor for you. Combining 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 moist situations in no time.

The sensor itself is advertised as Water Resistant but the breakout board for testing out this sensor is not! If

you want to use it in wet environments you'll need to pot the rest of the board in a wateproof epoxy!
