GSM GPS Based Smart Blind Stick

DOWNLOAD ABSTRACT

AIM:

Design and Development of GSM GPS based smart blind stick.

PURPOSE:

Normal blind sticks help blind people while walking. But they are not smart enough to guide all the way. Smart blind sticks can help in so many ways like location tracking and obstacle finding with voice feedback. Here we propose system like GSM GPS based smart blind stick.

DESCRIPTION:

This project includes GSM (Sim800C) module, which is connected to Arduino through UART. GPS module connected to Arduino through UART interface. IR sensors connected to Arduino digital pins. Ultrasonic Sensor connected to Arduino digital pins. Voice playback module connected to Arduino digital pins.

WORKING:

In this project IR sensors placed at bottom of blind stick to detect small objects. Ultrasonic sensor placed at middle of blind stick to detect obstacles. There is emergency button placed at top of blind stick to intimate about emergency. In emergency condition SMS will come to registered mobile number. Voice will play when any sensor gets activated. All this information will display on 16X2 LCD. SMS contains Google maps location. Using GPS location we can track easily.
