CBSE Science Fair Exhibition Project, “Faraday’s stick” Theme “Information and Education Technology” for Class 9, Class 10 and 12

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.
