This document describes an attendance monitoring system using Bluetooth. It consists of the following key elements: 1. Each student's smartphone is set up with an Arduino, Bluetooth module, WiFi module, voltage regulators, and real-time clock. 2. The system works by searching for and identifying each student's unique Bluetooth MAC address when they enter the classroom. 3. Student attendance data is stored and managed in a database using PHP scripting. This allows tracking attendance against timetables, teachers, and classrooms. 4. The system has potential applications for pedestrian traffic management and crowd detection/control. A working prototype is available online.

11. Some Technical Talks

12. 1.Bluetooth Module (HC-05) 2.0
The key player of this game.
1. It’s a Serial port Protocol Module.
2. Can work as both slave and master.
3. Bluetooth V2.0+EDR (Enhanced Data Rate)
3Mbps Modulation with complete 2.4GHz radio transceiver
and baseband.
4. Baud Rate- Depends on the model and usage.
Default- 9600 or 38400
5. AT Commands is the key feature for our application

13. 2.Wifi Module (ESP8266)
1. low-cost Wi-Fi chip with full TCP/IP stack and
MCU (microcontroller unit) capability
2. China’s invention – cheapest flexible wifi module
ever. Documentation was in Chinese for so many years
so was not in light in the tech world.
3. Using TCP/IP we can send datas over internet an even receive
by using a microcontroller!!!!
4. Cost even less then 3 dollars.

14. 3. RTC Module (DS1302)
1. The DS1302 trickle-charge timekeeping chip contains a
real-time clock/calendar and 31 bytes of static RAM .
2. The real-time clock/calendar provides seconds, minutes,
hours, day, date, month, and year information.
3. Only three wires are required to communicate with the
clock/RAM: CE, I/O (data line), and SCLK (serial clock).
4. Data can be transferred to and from the clock/RAM 1 byte
at a time or in a burst of up to 31 bytes.
5. The DS1302 is designed to operate on very low power
and retain data and clock information on less than 1μW.

15. 4.Arduino Mega

16. Wireless is the
big thing for
now and future
Reality Check
Applications

17. Pedestrian System
To be implemented by us..

18. Traffic Management
