Human Body Temperature Sensed Automatic Door Opening System

The automatic door opening systems are used in commercial buildings, shopping malls, theaters, etc. These systems are used to open and close the door when a person comes near to the entry of the door and close it after the person entered into the door. This kind of system can be built by using various kinds of sensors such as PIR sensors, Radar sensors, Laser sensors,and Infrared sensors etc. This project uses a PIR sensor to sense the infrared (IR) energy generated by the human body.When somebody come close to the door, the IR energy sensed by the sensor transforms and triggers the sensor to open and close the door routinely. Further, the indication sent to microcontroller to control the door.
