Just search the internet and you will find the complete technology to setup a manufacturing plant.The concept may look simple but don't try to design one with some IR sensors and retrofit in a home wash basin. It will never work. There is a huge difference between a school lab demo and a finished product from a hundred million dollar MNC. Just import the complete automatic faucet from China and install it. Visit this site and folow the links.You will become an expert on this technology.
