Hi,
I have a waterproof smartphone with sensors like barometer, gyro, accelerometer, microphone). I want to do an app that
1) detects that the phone is underwater: I though in using some reading from touch panel as water is electro conductive and it may provide me some reading to indicate that. Another idea is to use barometer to detect is underwater due pressure variation
2) Detect how depth underwater my smartphone is: I am trying to do that using the barometer.
Questions I have:
1) What would be a good sensor to detect my device is underwater?
2) Does the barometer works underwater? Is there any kind of correction factor to add/subtract in order to read proper underwater pressure values hence calculate depth?
thanks a lot!
