Allowing for the increase in depth of water when a person is in the bath, yet ensuring it is deep enough for comfort, the depth of water should be run no higher than 15cm. I will be testing my sensor between water depths of 2cm and 15cm, because these are the minimum and maximum levels of water that would normally be wanted. The sensor does not need o be able to measure water depths between 0cm and 2cm because it is unlikely this depth of water would ever be required, and if it was, then would run so quickly there would be no need for the warning system. I will be taking measurements with...
