Abstract: A container weight notification system including a monitoring unit. The monitoring unit includes a housing maintaining a weighing device, a microcontroller, and an alert device. The weighing device signals information indicative of a current weight of a container associated with the housing to the microcontroller. The microcontroller is programmed to prompt the alert device to generate a notification based upon a comparison of the current weight information with a maximum weight value and a minimum weight value, for example as a calculated ratio. Notifications are optionally delivered (wired or wirelessly) by the microcontroller to a remote computing device operating a notification application. The monitoring unit can be separate from the product container or integrally formed with the container.
