We present a self-powered compact hand-held device with bluetooth connectivity to access database. The devices are about a credit card size with a thickness of 12mm. One device based on multiple LED light system measures transmission of liquid samples (±2%). The other device, based on total internal reflection, determines the sugar content of liquids (±0.2 Brix).
