Mobility for people with visual impairments is a challenge in placeswhere there is no knowledge of obstacles. Research carried out inthis work identified that people with visual impairment have difficultieswith obstacles located above 1 meter. Thus, an approach isproposed to notify the visually impaired person through sound andvibration about such obstacles. The proposed solution is available onthe ThingSpeak platform and components such as microcontrollers(ESP8266 NodeMcu ESP-12), sensors, buzzer and GPS were usedin its development. Results confirmed that the proposed approachcorrectly identified the existence of obstacles with a height equalto or greater than 1 (one) meter in the way of visually impairedpeople.
