Overview
A contact-type object water content sensing device and method and a computer program product are presented. The device includes a power unit, a sensing unit, and an calculating unit. The sensing unit includes a substrate and a copper foil, and the copper foil is configured on the substrate. The sensing unit is used to contact a target object and a power unit is used to supply power to the copper foil. The copper foil when supplied with power forms an equivalent capacitor, and the equivalent capacitor has different capacitances in correspondence to a water content of the target object. The calculating unit is electrically connected to the sensing unit and is used to analyze the capacitance of the equivalent capacitor, so as to calculate the water content of the target object.Category
