Bus Information Alert for Blind Using Zigbee  


Nowadays, the blind people require other person’s help to recognize their bus. The main objective of this project is to help the blind peoples. By using this project, they can easily identify the particular bus in the bus stand through the voice alert system. This project is user-friendly and it works very efficiently.


The two main modules of this project are given below:

  • Bus stand module – It contains microcontroller unit, FM transmitter and Zigbee transducer.
  • User module – It contains Zigbee transducer, microcontroller unit, FM receiver.

When the blind person goes inside the bus stand, he can search the particular bus by pressing a switch in his module. Later, the microcontroller will send the data via Zigbee transducer. In the bus stand module, the other Zigbee transducer will receive the data and it searches the particular bus. By using FM transmitter, it will send the voice data to the user module. In the user module, the FM receiver will receive the voice data. In this way, the blind person will hear the Bus information through his head set.

In this project, we are using PIC 16F73 microcontroller. The microcontroller program is written in assembly language. This project is very helpful for blind people to recognize their bus in the bus stand.
