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 and a switch.
If any land slide or any water body is present infront 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 switch so he can hear the audio of the distance from any obstacle .
