The circuit is built with an arduino uno 16 2 lcd pir sensor connecting wires breadboard 1 k resistor power supply motor driver and dvd.
Motion sensor automatic door opening system.
They open the door when someone comes near the entrance and close it after sometime.
These days most automatic doors use motion detection sensors or optical sensors which are installed on the sides of the door to trigger the opening closing of.
Motion detectors or optical sensors.
An automatic door opener system is a simple project based on pir sensor and cloudx microcontroller which automatically opens and closes the door by detecting a person or object you must have seen automatic door openers in shopping malls and other commercial buildings.
The circuit diagram of an automatic door opening and closing system is shown below.
The hardware requirements of the human body temperature sensed automatic door opening system include a power supply microcontroller at89s52 at89c51 motor driver l293d dc motor push button pir bc547 led 1n4007 resistorsand capacitors.
You might have seen automatic door opener systems at shopping malls cinemas hospitals etc.
A number of technologies are available to design automatic door openers like pir sensors radar sensors laser sensors infrared sensors etc.
This pressure sensor would detect the presence of people in the area based on weight and facilitate the automatic opening and closing of the door.
