A Novel Approach of Smart Electronic Aid for Visually Impaired People using Arduino

The aim of this project is to provide low cost and efficient navigation aid for visually impaired persons who get a sense of artificial vision by providing information about the environmental scenario. The system is intended to provide the visually challenged an enhanced living and better walking experience. The design is incorporated with Ultrasonic sensors for Obstacle detection, supported by water detection sensors. The use of Ultrasonic sensor is used to find the obstacles in front of the blind person to guide this person on the correct path. Additionally, we are using a GPS module for tracking the blind person and GSM is also implemented for sharing the location of the blind people, in case of emergency. Temperature sensor and heartbeat sensor are used to check the health condition of the blind people, in this case, if the normal temperature level and heartbeat rate changes, the message will automatically send to the guardian through mobile phone and also it will be uploaded to the clouds for the future use. This research work explains about the setup we used for the implementation and design detail.
