3. INTRODUCTION
Purpose of the Project:
The basic function of the project is to alert parent through sms at which
the students report to college/school and leave from college.
What the project does to fulfill the purpose:
1. Conservation Of Time.
2. Day to day Performance of the child through Message.
5. Hardware requirements | software requirements
• 8051 series Microcontroller
• RFID tags and RFID Reader
• LCD
• Resistors
• Capacitors
• Diodes
• Transformer
• Voltage Regulator
• Crystal oscillator.
Keil Compiler
6. component’s explanation
• Microcontroller: It is the Heart of the circuit. We will be using ATMEL’s AT89S52 microcontroller. The
controller that we will be using is ATMEL’s AT 89s52, which is a 40 pin microcontroller with 32 I/O lines. The
controller communicates with the RFID reader & the PC using RS232 protocol for which MAX 232 IC is
required.
• MAX232:
Microcontroller communicates with the PC using its inbuilt Serial Port. The voltage levels
are 0 & 5 Volts, but for the controller to
communicate with the PC we are using RS232 protocol so for
converting the CMOS (0-5) voltage levels into RS232 (±12) voltage levels we will be using MAX 232.
• Gsm modem: To send sms
• RTC:
Real Time Clock (RTC) is used to storing the real time. A battery is provided to the RTC so
that even when there is a power failure the time is intact. The controller communicates with the RTC using
the I2C protocol.
• EEPROM:
EEPROM is used to store the LOG’s of the person entering or exiting the premise.
The EEPROM will contain the person’s ID, time of scan & if the person is entering or exiting. The controller
communicates with the EEPROM using the I2C Protocol.
• LCD:
We will be using 2-Line, 16 characters LCD. This will be used to display the real time, scan
successful or not and other such details.
• Power Supply: The complete circuit works on 5v this voltage is generated in the power supply section
which basically consists of a step down transformer, a rectifier & a voltage regulator.
• RFID Module: To read RFID tags.
8. The Advantages of RFID vs barcode technology:
• No line of sight requirement.
• The tag can stand a harsh environment.
• Long read range.
• Portable database.
• Multiple tag read/write.
• Tracking people, items, and equipment in realtime.
9. Advantages
• Store data on a tag
• Can be hidden
• Work in harsh environment
Disadvantages
• Lack of standards
• Short range
• Cost
