Project Name : Faraday’s stick
Theme Name : Information and Education Technology
Objective: To design a low cost, energy efficient obstacle sensor stick to aid navigation of old and blind people and help them sense the obstacle
around them.
Scientific Principle Involved: The project uses:
FARADAY’S LAW
The electrical energy powers sensors
The sensor transmits waves
These waves bound and echo back when there is an obstacle in front
The sensor receives the reflected waves.
The output of the sensor is attached to a buzzer which sounds when an obstacle is detected and LED glows on basis of distance.
Material used for the project: Stick, Magnet, Copper wire, Cylindrical Tube, Capacitor, Resistors, Ultrasonic Transmitter and Receiver, Circuit Board, LED’s, Header, Jumper, Buzzer.
Working Investigation/Findings:
Old persons and blind persons of low vision respondents frequently encounter intrusions into the path of travel
Old persons and blind people find audible signals at crosswalks the most helpful solution to address barriers to house wide /citywide navigation as it helps old persons and blind persons to walk more confidently.
Utility of the project:
This project can help old person and blind to walk safely
It can be used as a Demo experiment in class
Name of the School: Mata Jai Kaur Public School, Ashok Vihar, New Delhi.
