Controller Based Smart Blind Stick for People with Vision Loss

One of the biggest problems faced by the visually impaired is navigating from place to place, be it indoors or outdoors. The main aim of this work is to help the visually impaired person to remotely locate his/her stick using a RF remote. This system incorporates with buzzer and attached with multiple sensors to provide high security to the visually impaired people while walking. Now a days safety is main important cause to the peoples while walking or driving and many more places. The system provides the high security and show way to walk, this system can monitor the blind person position using mobile, an emergency alert message will be sent along with the exact location. The system has obstacle sensor, soil sensor and stair detection sensors, so that it can detect obstacles/ steps automatically and gives alert. By using soil moisture detector used to detect the moisture in the soil and gives alert accordingly. This system can be very useful to peoples to show correct path while walking on the floor or steps and many more places. The system can be interconnected with the microcontroller and alert the respective persons when any emergency occurs. This tracking system is composed of a GPS receiver, Microcontroller and a GSM Modem. The Microcontroller processes this information and this processed information is sent to the respective numbers.
