Project Name : Universal Aid for Visually Impaired
Theme Name : Health
Aim:
1. Cane mounted knee and ground above obstacle detection and warning system using infrasonic beam to enhance the horizontal and vertical detection range.
2. User triggered bus identification system using radio frequency.
3. Water detection system.
Working:
1. Object is detected using infrared sensor and producing a voice output to alarm the user.
2. Each bus module transmits RF signals which are received and sequentially spoken out by the user module.
3. Water detection: Water is sensed using an incomplete circuit, which gets completed when it comes in contact with water. This is because impure water conducts electricity.
Advantage:
Recording or voice output can be done in any language with the help of microphone depending on the user‟s needs. It does not depend on the position of the bus (right, left, back or front).
Cost: 1500/-
Future Scope:
1. The cost can be reduced further.
2. The detection process can be made more accurately by using ultrasonic sensor.
3. Alarm can be made into use.
