RESULTS:

Thus, an ambient non-obstructive display device was created to serve the purpose of a smart reminder to switch off lights in various rooms while exiting the house. This personal device could be installed in your homes. The smart door knob is an extension of the regular door knob but now feeds on data from the rooms and gives us a display output which is meaningful and useful. A system to track and remind humans about the status of various rooms was successfully built and installed. The problem statement chosen was successfully solved.
