Next, we investigated the float volume needed to match the average weight everyone, weight solids to react with water to form an integrated gas can fit a maximum volumetric strain of the float. And our research also suitable for water pressure device when the user activity sank to certain depths to choose (set) pressure sensors suitable water. Our objective is to create a product with automation technology, works well and smart, compact size and does not affect the fashion trends of the user.
