Smart Safety & Advance Blind Walking Stick

   In Smart Safety & Advance Blind Walking Stick There Is GPS Module Which Use To track The         Person Location.  And There Is RF Module is there to Find Her Stick Where he Kept, There Is          Voice Module Is There Which Use as Feedback System to User. There Is Ultrasonic Sensor is Use       to Detect Any Object In Between the path is there is obstacle in path then in Give feedback to user     in voice and Vibration Mode also there is Water Detector and day and night sensor is there to know     the user and gsm Module is there to update location on web or sms form & if there is any                     emergency is there then send location of User To web or to person Test Sms or even he can call the     user in system predefined no communicate fast for and any emergency Condition.

Ultrasonic Based Blind walking stick

Blind stick is an important for visually disabled people for navigation. Here an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Ultrasonic sensors to detect obstacles ahead using ultrasonic sensor. On sensing obstacles the sensor passes this data to the microcontroller.

The microcontroller then processes this data and calculates if the obstacle is close enough or not. If the obstacle is not that close the circuit does nothing. If the obstacle is close then microcontroller sends a signal to sound a buzzer and vibration feedback. Also if it detects water and alerts the blind with same feedback with different frequency. One more feature is that it allows the blind to detect if there is light or darkness in the room. also help the blind people to find their stick if they forget where kept it. Then A wireless RF remote is used for this purpose. Pressing the remote button sounds a buzzer on the stick which helps the blind person to find their stick. Thus this system allows for obstacle detection as well as finding stick if misplaced by them.
