Referring to the schematic block diagrams shown in fig. 2 and 3, the color sensor 200 and the capacitive sensor 300 are respectively electrically connected to the comparison module 400, wherein the color sensor 200 is used for collecting light signals, for example, the container body 100 is filled with rice to be measured as a light source, and the color sensor 200 converts a virtual signal (color signal of light reflected by the rice) into a digital quantity (colorimetric LAB metric) for the comparison module 400 to recognize and calculate.
