I am trying to do an algorithm to measure the underwater pressure and how depth I am. My Android device is water proof and has a barometer sensor. I am getting strange readings from barometer when device is underwater so I am not sure if that sensor works in underwater condition.

Does anyone know if the barometer for android devices (Galaxy S7 device, pressure sensor LPS25H from STMicroeletronics) works underwater? Shall I add a kind of correction parameter in the algorithm to get proper preassure measures when underwater?

thanks!

  • Sounds more like an electronics/physics question. Of course the sensor's intended operating range might easily be exceeded underwater if it's designed for a realistic atmospheric pressure range. And what effect does a possible air bubble stuck between the sensor and the water have(?) – Markus Kauppinen Oct 07 '16 at 17:57
