The first -ever miniature infant scale adopts a design concept which is similar to the bubble cloth. Simply push the power button and the air will be pumped in automatically. The infant lies comfortable and safe on the air cushioned platform. After usage, simply push one button and the air in the cushion will be released automatically for the convenience of storage or carriage since it is only palm size when folded. The product recognizes the difference in air pressure to detect the weight. The pressure sensor transforms the change in pressure into a voltage signal and through an algorithmic program that determines the weight.
