AUTOMATIC DOOR

This is a model on automatic gate/door. Sometimes when we are busy, we find it difficult to answer the bell and open the door, or to some people it is physically challenging to get up and open a gate often. So, we have designed this simple yet effective answer to the above mentioned problem. Here, we are using an infrared sensor which detects the presence of a person in front of the door and automatically responds by activating two geared motors which actuated the opening and closing of the gates/doors.
The sensor can be placed tactically in case there is a security concern and its position is disclosed only to trusted individuals.
