An Android system mobile application was fully developed using the MIT App Inventor platform, which can be then used to monitor the overall progress of the production line. It displays the outputs of how many bottles filled, how much liquid is left, and how many caps consumed after installing up counters in the system, then it does raw data processing and sends messages to an online google sheet that displays warnings in case the sub-tank of the liquid runs out, or the bottle caps need to be refilled. Moreover, the user can contact the liquid supplier, or the bottle caps supplier to get refills, using the mobile application. A milk production line was assumed for the development of this mobile application.

A live App Demo is available on the website platform on:
