Is LPS25HB Waterproof? (Qwiic Pressure Sensor)

[This is the sensor in question. Can the sensing part be exposed to water?

The sensor integration guideline for LPS25HB by the manufacturer [at this link says that a filter membrane can be added to protect the sensor from water. Does the sensor contain this protection?

Thank you.](https://www.st.com/resource/en/application_note/an4672-lps22hblps25hb-digital-pressure-sensors-hardware-guidelines-for-system-integration-stmicroelectronics.pdf)](Qwiic Pressure Sensor - LPS25HB - SPX-14767 - SparkFun Electronics)

Hi @baigyanik,

The sensor package itself does not include a membrane. You would need to add one over the opening (vent aperture) in your enclosure - as shown in Figure 2 in the integration guide.

Best wishes,
