Bluetooth Enabled Smart Device for Attendance Monitoring with Feedback System
Nowadays in the modern trend Communication takes place through wireless only. Mostly is Wireless Communications there will be a Transmitter unit and a Receiver unit and the type of transmission can be Infrared, RF, Bluetooth etc. Here, the problem is the communication is Simplex communication i.e., One end we can transmit data and on the other end we can receive data. No duplex communication is possible. To overcome this factor, we can develop a project in which we can send and receive data in wireless.
This will be useful for many applications such as in hospitals, schools, colleges etc. Here in our project we have an idea to have an Hand held device in which we have a transmitter and a receiver unit fixed in that device where we can enable the transmitter, Send a message and deactivate it. Then Activate the receiver unit wait for the acknowledge or for the data to come in and deactivate it. The other side also has a similar unit.
For the Hand Held device we have decided to use a pic microcontroller with LCD Display and Keypad.
We have decided to use a Bluetooth Transmitter and Bluetooth Receiver unit whose frequency is 2.4Ghz.
