Automatic Door Sensor Circuit

An automatic door opener system is a simple project based on pir sensor and arduino which automatically opens and closes the door by detecting a person or object.

Automatic door sensor circuit. Where as soon as a person approaches the door at about 2 or 3 feet the door. In this arduino based project we have tried to replicate the same system by using a pir sensor. Here is a very useful project of an automatic door sensor light circuit. A number of technologies are available to design automatic door openers like pir sensors radar sensors laser sensors infrared sensors etc.

The circuit can also be used for variety of. Pir sensor based security alarm system. Hence if the circuit detects any human passing in its region will enable the motor to operate the door automatically. When you open the door and get inside and close it automatically when you get outside.

Automatic door sensor light. You might have seen automatic door opener systems at shopping malls cinemas hospitals etc. Thus the motor driver controls the motor interfaced to it and fixed to the door. The circuit will automatically activate light of a room storeroom washroom etc.
