Story

How can we engineer a system that ensures both safety and convenience in a store? We have 5 components installed on this device. Firstly, we have an Automated Door where users may just enter the door without pushing or pulling the door. Secondly, we have an Inventory Stock Checker that alerts staff when an item is low in stock. Thirdly, we have a Product Information Scanner where customers can scan a product and information is shown. Forth, we have an Intruder Alarm where once the shop is closed and someone tries to break in, the alarm would be triggered and activated. Lastly, we have a Police Button Alert in case there is a robbery, and a button can be activated and the police would be contacted immediately.
