IoT based Smart Assistance for Visually Impaired People

Independence is how you build to achieve your dreams, goals, and goals in life. According to the World Health Organization (WHO), worldwide, 285 million people are blind, of which 39 million are blind, and 246 million are partially sighted. Visual impairment is the absence of intelligent vision as a result of physiological or neurological factors. This paper presents a model that integrates distance and water detection with an ultrasonic sensor and a rain sensor. The proposed project initially uses an ultrasonic sensor to detect obstacles using ultrasonic waves. Upon detecting an obstacle, the sensor transfers this data to his Nodemcu. Nodemcu will process this data and calculate if the obstacles are close enough. If the obstacle is not too close, the circuit does nothing. When an obstacle approaches, the Nodemcu will send out a signal and sound a buzzer. It also sounds another buzzer when it senses water to warn the visually impaired. Using web-based servers our model also includes the provision of getting help in case of emergency. Electric walking sticks help the visually impaired by providing more convenient living opportunities. The main purpose of this paper is to make our knowledge and services accessible to the visually impaired and people in the disabled community.
