applications of microcontroller based automatic door open and closed system using ir sensor pdf

This is a good Electronics Project report on Automatic Door Opening System Using IR Sensors which is used to automate door opening. Some of the main component required for this project are Power supply, ATMEL (AT89S52)Microcontroller, Stepper Motor & IR sensors. This report start with the introduction to embedded systems. In this system whenever the infrared sensor senses the obstacle and the signal is sent to the microcontroller. Then the microcont ....etc

An electronic lock (or electric lock) is a locking device which operates by means of electric current. Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to the lock. Electric locks may be connected to an access control system, the advantages of which include: key control, where keys can be added and removed without re-keying the lock cylinder; fine access control, where time and place are factors; and transaction logging, where activity is recorded. Electronic locks can also be remotely monitored and ....etc

PLC BASED DOOR OPEN AND CLOSE SYSTEM



WORKING PRINICIPLE:
The microcontroller based Door locker is an access control system that allows only authorized persons to access a restricted area. The system is fully controlled by the 8 bit microcontroller PLC. The password is stored in the EPROM so that we can change it at any time. The system has a Keypad by which the password can be entered through it. When the entered password equals with the password stored in the memory then the St ....etc

ABSTRACT

Here, proposing a novel wireless access monitoring and control system based on the digital door lock, which is explosively used as a digital consumer device. Digital door lock is an electronic locking system operated by the combination of digital key, security password or number codes. This paper presents a prototype of the proposed system and shows a scheme for the implementation. To implement the system with ZigBee network protocol, four types of modules are developed, ZigBee module, digital door lock module, human ....etc

On the PLC in the automatic door control system
In supermarkets, public buildings, banks, hospitals and other imported, often using the automatic door control system. The early automatic door control system uses relay logic control, has gradually been phased out. PLC controlled automatic doors as a low failure rate, can be * high, convenient maintenance, which is widely used.

two basic requirements for automatic door control

1 was close, the door should automatically open.

2 door opened, the state should be kept open until the d ....etc
