Story

Our project will provide flexibility of controlling crowd in highly demanding service areas like Banks, Malls, Grocery stores and a lot of place like this.

When we heard about this challenge, we started thinking about suitable a solution as well as we decided to make it as easier as possible. After thinking some days and analyzing our daily life. We found that, if we make a system that could help us to control crowd in highly demanding service places like Banks, Malls, Grocery stores etc. Then it will be a great solution for those peoples who spend hours of their daily lives to control crowd in these places.

As a result we came with our solution "Rekha 2.0"

Rekha 2.0 is a Arduino based crowd controlling and sanitizing system. We can connect it to the entrance gates of places like Banks, Malls, Grocery stores etc.

Its working with proper explanation and model is shown in the video.
