Abstract: An apparatus powered by batteries may include a first processor and a second processor. The first processor may consume more electrical power than the second processor. The second processor acquires data from one or more sensors. At a predetermined time or other trigger, the second processor activates the first processor that is then used to send the acquired data to an external device. For example, items are stowed on the apparatus that includes weight sensors. The second processor awakens hourly, acquires weight data indicative of the weight of items stowed on the apparatus, and returns to a sleep mode. After 24 hours of acquiring weight data, the second processor activates the first processor to send the accumulated weight data to an external device, such as a server, using a network interface. Power consumption is substantially reduced, allowing the apparatus to operate without external power for extended periods of times.
