Makers, developers or hobbyists needing to sense pressure in a damp environment may be interested in a new arrival at the Adafruit online store. Adafruit has this week announced the availability of their new LPS35HW Water Resistant Pressure Sensor that will allow you to see relative changes in pressure as well as the absolute pressure.
The LPS35HW sensor combines protection from water intrusion with support for high precision relative and absolute measurements, and drivers are available for CircuitPython, Arduino, and Raspberry Pi, and support for I2C or SPI (Arduino only SPI support, for now).
“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.”
Priced at just $12.50 the Water Resistant Pressure Sensor is now available directly from Adafruit and specifications include a :
– Pressure sensor with water resistant package
– 260 to 1260 hPa absolute pressure range
– 24-bit pressure data output
– 16-bit temperature data output
– ODR from 1 Hz to 75 Hz
– SPI and I²C interfaces
