A Low-Cost Implementation of an IoT based Food Ordering System

This paper proposes the use of an IoT-based food ordering system that would be a very actionable and profitable system in the coming age of digitization. This system functions to automate and simplify the entire process of ordering food in public places such as restaurants, food courts, etc. wherein it would aid in reducing the load on manpower and fastening the service at all times, whilst making the entire process cost-effective for the restaurants. In a nutshell, the system constitutes various on-table devices that connect each table to a monitor display in the kitchen via WiFi. A device, with TFT touch display mounted on it and connected to the NodeMCU, on each table enables the customer to place the order conveniently which is further sent across on a web server using the inbuilt ESP8266 WiFi module on the NodeMCU which is displayed on the monitor installed in the kitchen.
