smart lunch box

The paper discusses the concept of creating an insulated lunch box that limits the heat transfer with its surrounding. In addition to limiting the heat transfer, the concept also proposes a method with which heat can be added to the system. This, in turn, prolongs the period where edibles can be stored at the desired temperature. A Thermoelectric Cooler is incorporated which makes possible the inception of two separate compartments in the lunchbox which stay at different temperatures to make possible the storage of hot as well as cold food inside a single lunchbox. Due to the increasing importance of healthy and warm food, one can have midst the work, the paper  ascertains  the need to understand the potential working mechanism of this project. This concept can possibly change the conventional way  of carrying food by introducing an additional cold compartment to store the food in addition to a hot one. The design of the prototype is discussed. Various electronic components to be used are discussed and the working of the prototype is explained.
