Rfid door lock with active tag.
Rfid based door lock system ppt.
These kind of door locks are designed with one or more keys but for locking a large area various locks are needed.
The circuit diagram of arduino and rfid based door access system is shown in figure 1.
Rfid and arduino based automatic door lock system.
3 1 basic explaination of rfid technology.
After detecting and receiving rfid tag data through a serial interrupt routine microcontroller searches the nv ram for this number.
This rfid based access control system is built around arduino uno board rfid reader module solenoid lock and a few other components.
Proposals from partner companies.
Entrance monitoring controller comprises of an rfid reader a gsm modem a nv ram door lock alarm scroll keys and 16x4 lcd.
The basic necessity of security can be attained by designing various door locks such as mechanical locks or electrical locks.
The circuit basically consist of arduino uno central control unit rfid receiver module rfid tag solenoid lock and few other electronics components like resistor capacitors diodes transistors etc.
Fingerprint door lock renesas.
Circuit description of arduino and rfid based door access system.
All interfaced to at89c52 microcontroller as shown in fig.
Rfid is a non contact automatic identification technology that uses radio signals to identify track sort and detect a variety of objects including people vehicles goods and assets without the need for direct contact or line of sight contact as found necessary in bar code technology.
By using arduino it is easy to access and works very quickly while burning the code it is like plug and play device.
In countries like india such automatic systems are not cheap by any yardstick.
Rfid based security and access control system is more secure and fast responded as compared to the other system like biometric.
Generally traditional locks are heavy and that are not strong as they can damage simply by using some tools.
The advantage of the rfid system is contact less and works without line of sight.
Weimplemented a security system containing door locking systemusing passive type of rfid which can activate authenticate andvalidate the user and unlock the door in real time for secureaccess.
The rfid module works as sensor.
A micro chip in a label used to transmit data when the label is exposed to radio wave.
