This is based on an automatic and precise door opening system based on human movement, sensing near the door. In places like hotels, Shopping complexes, and offices automatic door opening can be a tedious task and sometimes  requires hiring a person just for the sake of opening door whenever a person arrives. This project proposes a system that allows for automatic door opening solution by sensing human presence near it. Our system achieves this  functionality with the help of PIR (passive infrared sensors) sensors. Every live body emits some infrared energy. This energy is sensed by a PIR sensor from a good distance. This signal is then processed and door is opened and closed based on this data. When a living being arrives within the sensor range, it detects its presence and sends out a command that opens the door. The door then automatically closes after a specific time delay if there is no further motion near the door. The system can be later enhanced by integrating counter mechanism so as to keep track of the number of persons inside the facility.
