i am researching for a project for industrial automation . in this i am having one concept that is following below
if any one of person is in room the electrical power should be connected in this time one or more persons are entering in side that room at that time also that power should be ON .Now that persons who are all inside that room one by one is coming out that power should not be OFF but the last person who is coming out side off the room that power should be OFF
this is my concept of my project for this concept please design a circuit for me please send me replay for this concept

You have to count people with optical switches or infrared detectors. Then using dsp or up processors and figure how best to establish number of people in room.
A pair of optical switch-sets for every door that leads to room. Only if object cuts both beams then you count one.
it is the idea you have to develop, circuits are on the web.
