So i tried to solve this problem by proposing a system consisting of ultrasonic sensors and ESP32 which detects and analyses the obstacles and generates the alarming signals according to the distance of the object. s, which includes an ESP32, an Ultrasonic sensor, a speech playback module, a GPS receiver module, and a GSM. Using an ultrasonic sensor, the Smart Stick locates impediments and feeds the information to an ESP32 for proximity calculation. The GSM module then determines the user's location and sends messages to their family based on sensor data, with the voice playback module providing vocal help to avoid collisions with obstructions. Because of its user-friendly control mechanism and ability to detect obstacles in all directions, the Smart Stick offers a comprehensive solution for those with vision impairment or blindness. The Smart Stick is a useful navigational aid. Using its GSM module, it can detect impediments in all directions, offer voice help, and give loved one’s security. Anyone with a visual impairment can utilize it thanks to how simple it is to use.
