Bus Information Alert for Blind Using Zigbee
Abstract
In bus stands, blind peoples feel very difficult to identify
their particular bus. They need other's help to identify the bus. This project
is developed for the blind peoples to identify their bus through voice alert
system using Zigbee.
It consists of two modules called user module and bus stand
module. The user module consists of microcontroller unit, FM receiver and
zigbee transducer. The bus stand module consists of zigbee transducer,
microcontroller unit and FM transmitter
When the blind person gets inside the bus stand, he searches
the bus by pressing a switch in his module. The microcontroller sends a data
through zigbee transducer. The other zigbee transducer connected in the bus
stand module receives the data and searches for the particular bus. Accordingly
it sends the voice data through FM transmitter. The FM receiver connected with
the user module receives the voice data. Thus the blind person hears the Bus
information through his head set.
This project is very useful for blind people to identify
their bus in the bus stand. The microcontroller used in this project is PIC
16F73. The microcontroller program is written in assembly language
