Wastage of electricity is one of the major problem which we are facing now-a-days. In our home, school, colleges or industry we see that fan and lighting point are kept ON even if there is nobody present in the room or area and passage. This happens due to negligence or because we are in hurry. To avoid all such situations this proposed work is designed. This proposed work has two modules, first one is known as “Digital Visitor counter” and second module is known as “Automatic room light controller”. One of the benefit of this proposed work is “Visitor counter” which measures the number of people entering in any room like seminar hall, conference room, hotel rooms etc. This function is implemented using Infrared transmitter and photodiode.
