Description of the project:

This is one of the best electronics project ideas for blind people. This project has a GPS modem and a GSM modem. GPS tracker for Blind people project sends SMS to the family members of the Blind person. This SMS contains the Longitude and Latitude of the person. This project also has a Keypad that has 4 keys. This keypad can be used by a visually impaired person to send emergency messages to family members. 4 Keys have respective 4 emergency messages.

GPS modem continuously sends data string to the Microcontroller. This data contains various type of information. It includes Longitude Latitude of the place where project is currently situated. Thus Microcontroller gets co-ordinates of the place. Then it sends SMS after periodic interval of time, for example after every 1 minute.

Every alternate day we hear news about person missing. Many of these include blind person. Some of these blind people are never traced. However with the use of the advanced GPS blind person tracker system, family members can find blind person in few minutes. GPS based tracker for blind person project solves this problem.

It is really difficult for blind person to move in this world. There are chances that they can get lost; in such cases it is really difficult for their family members to find them. Blind person has to carry this project in his/her bag.

Description in detail:

Various important blocks of the system are:

1. Microcontroller: We have used AT89s51 microcontroller which is a series microcontroller. 8051 microcontroller communicates with Keypad, LCD display, GSM modem and GPS modem.
2. LCD display: This is an important part while developing the project. However it is a non-mandatory component of the circuit
3. GPS modem: Data sent by GPS contains various type of information including Longitude and Latitude of person’s current location.
4. GSM Modem: GSM modem sends SMS with the help of AT commands sent by 8051 microcontroller.
5. Keypad: It is used to send an emergency message to the family member.

Applications of GPS tracker for Blind people:

There are many Applications of GPS based tracker for Blind person using GSM technology, few of them are listed below:

1. This project can be used for Blind person.
2. GPS for blind person project can also be used for tracking visually impaired people, senior citizens, elderly person in our home.

Advantages of Blind person tracking system using GPS and GSM technology

1. This is one of the GPS projects for blind which is very easy to install and easy to use.
2. A partially sighted person can be immediately tracked using the projects for blind people.

Future Development:

1) We can add obstacle sensor and add more features to blind stick project using 8051.

Video of the GPS tracker for Blind people project

YouTube video coming soon. Video for this project is not available right now, we are planning to upload a video soon. Meanwhile, you can watch a video of another project in the category: GPS based project.

Questions and answers about this project:

Question: Can we use our mobile phone instead of a GSM modem?

Answer : No, we can not use mobile phone in gps for blind people project to send SMS.
