Vending Machine Electricity Usage Optimizer Using Automated Relay and AI for Smart Retailing Based on the Concept of Internet of Everything (IOE)

Modern vending machines operate to serve the consumer easy-access demand for daily items such as food, drinks, or books. Purchasing processes are carried out via automation from item selection, payment, up to the item dispensing are done without interaction to the human and this can be carried out for 24 hours a day and 7 days a week. However, the vending machines operates for 24/7, consumes the same electrical load regardless of if there is a transaction. Despite the advancements of Industrial Revolution 4.0 (IR4.0) in many sectors, electrical power of vending machine is yet to be optimized. This research aims to optimize vending machine power consumption by using camera to detect human near to the vending machine and relays to control the power usage. Human can be detected via camera via Artificial Intelligence (AI) and this becomes the input to the Smart Relay. Abnormality such as electrical leakage that draws more power can be detected as well. IoE dashboard is developed for vending operator to monitor the power usage, leakage potential, optimization, and prediction of power consumption. The system saves about to 50 percent of electrical power usage in the vending machine and low energy wastage while maintaining the same vending machine capabilities.
