A mosfet transistor or a servo to trigger the door required 5.
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.
An arduino board i used the arduino uno rev 3.
Doing this would relieve us from worrying if the chickens were safe at night and to be able to leave the house when we wanted this door will be located on the side of the coop.
The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.
A button swicth ir sensor etc.
The door sensor is also known as entry sensor contact sensor or window sensor.
The project generally relates to an automatic opening and closing of door which will sense person or object approaching door and open automatically.
You might have seen automatic door opener systems at shopping malls cinemas hospitals etc.
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.
This hack from sieuwe elferink takes care of that for you using an arduino uno for control.
To tell when to open the door.
The project generally relates to an automatic opening and closing of door which will sense person or object approaching door and open automatically.
This system is controlled by arduino micro controller.
A number of technologies are available to design automatic door openers like pir sensors radar sensors laser sensors infrared sensors etc.
Wood plastic sheets acrylic etc.
Material for making a case to hold the components eg.
Tired of doing the mundane task of opening your door.
I wanted a small door to open automatically via arduino morning night to the outside world.
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.
