Auto Open Door Arduino

When someone comes within 50 cm of an ultrasonic sensor attached to the door the arduino uses an h bridge relay to power a windshield wiper motor which opens and closes it via a linkage setup.

Auto open door arduino.

Above in the code there is a config part just like in the picture above. 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. Arduino nano v3 battery 9v dc. Material for making a case to hold the components eg.

A mosfet transistor or a servo to trigger the door required 5. This trigger voltage goes to a ac to dc diode bridge converter and then through the dc voltage sensor to the analog input a0 if analog input a0 returns a reads more than 4 volts then digital i 0 pin 12 becomes high and triggers the 5v relay which is connected to button of door phone that opens the door. An arduino board i used the arduino uno rev 3. You must have seen automatic door openers in shopping malls and other commercial buildings.

Click the clone download button and click download as zip. They open the door when someone comes near the entrance and close it after sometime. The project generally relates to an automatic opening and closing of door which will sense person or object approaching door and open automatically. An automatic door control system includes a sensor for sensing person or object approaching door.

This system is controlled by arduino micro. Then unzip the package and open the automaticdoor ino file with the arduino ide. To tell when to open the door. In the arduino ide you can see the code.

Closed limit sensor status active when the door is fully closed opened limit sensor status active when the door is fully opened open command signal active when the remote controller is pressed and the radio module activate a relay note.

Wood plastic sheets acrylic etc. Automatic doors are commonly found in retail stores supermarkets and the like. A button swicth ir sensor etc. Where as soon as a person approaches the door at about 2 or 3 feet the door automatically slides open.

The project concerns about automatic door opening and closing system. Pir sensor based automatic door opener project using pir sensor.
