This project is implemented by using microcontroller. Here we will check the RFID tag, along with a password associated with the tag, to secure the system.
Working of the entire system and role of each section can be understood throgh the below block diagram. This RFID is working at baud rate of bps.
RFID based Secured access system using 8051 microcontroller (AT89C51)
Here we have used a 4×4 matrix keypad for entering the password to the system. Here you can see the tutorial: LCD interfacing with microcontroller.
If data is matched with predefined data then microcontroller ask for password and after entering password microcontroller compare password with predefined password. If password match gate will open otherwise LCD show Access denied and buzzer start beeping for sometime. And buzzer is connected at P2.
And keypad is connected at PORT0. Keypad row are connected at P0.
Here we have some function that we have used in our program. In this we have configured bps baud rate at And then match the password. Quote and Order boards in micrlcontroller on https: U2 is LD motor driver IC.
Sir can you provide the hex code. Is this code can be compiled in any c complier or any specific compiler is there? Use Keil uvision Software.
If i wanted to add more tags and passwords how will i do that? Or you can modify the code to add IDs on run time and share here for the community.
What RFID module is that where can i get it from? I started microcontrollfr Carrier in Electronic Lab and having more interest in doing projects as hobby.
Earlier I did in I used to invest money to purchase sensors and processor and doing myself in House. But main technical supports are from NET, like you people. But now-a-days people are crazy to put their project as youtube without code and circuit diagram. So some time people like me are blinking. But you have given the project in detail. It is very nice of you.

By your this basrd of helping, you can develop many electronic engineers in India. Pl send your mail id if u like to have contact to my mail id . Thanks Abi Regard from Pradeep.
Hi Pradeep, Thanks for your encouraging words! How to set pass key in the access card?
RFID BASED SECURED ACCESS SYSTEM USING MICROCONTROLLER (AT89C51 | Venkatesha M –
Is this a correct code or is it having any errors.?? If so please send me the correct code If possible hex securihy. Sir, I tried the microcontrooler code given above, but could not understand the flaws I’m doing this project and I want a schematic file to run a proteus simulation.
Can u please email me the file. Sir I need a code for storing 4 mobile no. After loading the hex file ,the no. LCD interfacing with microcontroller Driver Section: Get Our Weekly Newsletter! Log in or register to post Comment.
