Interactive lunch box for personality developments of kids

it weighs the food and translates the data to the kid's pet toy and to a mobile app which keeps track of the kids stats health 

The pet is a virtual self of the child, its health is connected to the kid's, hence the kid has to take care of himself to take care of his pet

How it works

The lunch box

The case of the the Lunch box senses the weight of the food using a Force Sensitive Resitor(FSR) and sends the data to the pet and the app , Indicating the amount of food eaten by the child

The case also provides instant feedback using LED lights

Switch to turn on only the case opens

Led lights to indicate the amount of food

FSR to measure the amount of food
