Abstract
This disclosure describes, in part, systems for enabling facilities to implement techniques to identify items using weight sensors. For instance, a first weight sensor may determine a first weight associated with a first item, where the first item is priced per unit weight. The first weight sensor may be located within an inventory location associated with the item or a station that weighs and prices items. A second weight sensor may then determine a second weight of a second item. The second weight sensor may be located within the station or a tote, such as a shopping cart. A system may then use the second weight and the first weight to determine that the second item includes the first item. In some instances, the system may also use locations of the weight sensors, a time of flight of the item, and/or other information to make the determination.
