Customer Following Trolley using ESP32

In the past few decade the shopping mall were introduced in the metropolitan cities that made customers buy all kind of their daily commodities which are available easily in one place that is in one mall. In order to add the items in the cart supermarkets has brought moving trolleys. Once after we add items in the trolley it becomes difficult to move to the billing counter due to overweight. To overcome such issues many models have been proposed so far but due to its complexity in design and high maintenance cost these models are not yet implemented in reality and remained in the development section. Hence, we have proposed a model in which modern components are implemented that supports wireless internet connection and Bluetooth such as ESP32, camera module and NODEMCU. These works perfectly without any need of external source. Using this we have build a system that follows the customer during their shopping and they do not need to move their trolleys.
