Code 264 ADVANCED INFORMATIVE BLIND STICK USING GPS AND GSM

This project is designed for the visually impaired persons as they find themselves challenging to go out independently. This stick will help blind person by providing more convenient means of life. This project will have an ultrasonic sensor to sense the distance from any obstacle, soil moisture sensor to sense any slippery land or any water body, fire sensor to sense the fire, Bluetooth app installed in his smart phone which helps him to hear the audio, GPS to know the location of the blind person, GSM to send SMS regarding location and two switches.
If any land slide or any water body is present in front of the blind person then the soil moisture sensor senses it and the blind person can hear the audio through the Bluetooth app that “water body detected” so he can change his direction.
If fire is detected by the fire sensor the blind person can hear the audio through the Bluetooth app that “fire detected” and he will be alert. When the obstacle is near to him he can hear the audio of the distance from the obstacle.
Suppose the blind person wants to know the distance from any obstacle he can press the first switch so he can hear the audio of the distance from any obstacle. If he feels he is in critical condition he can press the second switch so the GPS will read the location of the blind person and SMS regarding location is sent to the care taker of the blind person through the GSM.0
