Abstract
A weight sensing device includes a casing, a weight sensing module and a light emitting module. A container placing area and a light emitting area are defined on a surface of the casing and staggered with each other. The weight sensing module is disposed in the casing and corresponding to the container placing area. The weight sensing module records a weight threshold. The light emitting module is disposed in the casing and corresponding to the light emitting area. When a container, which contains a substance, is placed on the container placing area, the weight sensing module senses a current weight of the container and the substance and compares the current weight with the weight threshold. When the current weight is smaller than the weight threshold, the weight sensing module drives the light emitting module to emit light, which is projected through the light emitting area.
