Product Design

If you want to build electronic circuits, you need to connect the components of your circuit somehow. If you expect to make your circuit work more than just a few times, you need a solid way of connecting them. You need to create a printed circuit board (PCB). "I started playing with electronics as a hobby when I was 14. Since then I have finished a Master's degree and founded two electronic design companies."

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

It is the purpose of this book to explain practical construction projects in these areas using the latest types of integrated circuits. Each project has been planned for simplicity and efficiency. That is, printed circuits have been avoided, the most practical hardware has been chosen in each layout, and battery operation has been utilized throughout.
