Abstract

Abstract: In this research paper, we place emphasis on the blind individuals within our society. The construction of our paper involves the prototyping of features and real-life applications. Our primary focus is on IoT in our research, utilizing a myriad of sensors to enrich our study further. Our project is adorned with GSM, the heart of IoT. It can detect the location of the blind individual and generate necessary messages based on different sensor readings, transmitting this information to the user's relatives. Through the use of multiple sensors, our stick is capable of issuing commands that can be likened to the eyes of a blind individual. We also employ an indicator to confirm that the user is blind. Our stick has the capability to identify any obstacles in the vicinity of the blind person, including those on the left, right, up, and down. The control system is significantly straightforward, enabling any blind person to operate it with ease. Introduction : Blind people encounter numerous challenges daily, one of the key ones being navigating the streets. The twofold problem of abundant vehicles and an array of obstacles potentially blocking their path necessitated a solution. Hence, we designed a smart blind stick, utilizing the Internet of Things (IOT). This stick employs an ultrasonic sensor to scan in front for obstacles, and it's connected to a GPS to aid others in locating the blind person. In unfortunate instances of accidents involving a blind person, our device can send an SOS message via the GPS module, alerting nearby individuals to the situation. We believe that society needs to provide care and attention to blind people, enabling them to lead confident and independent lives. The safety of blind individuals during their walks remains a significant concern. Most opt for a blind cane, the simple structure and singular function of which allows them to find their way by tapping on the ground or circumnavigating obstacles. Despite the ease of use, these canes have evident limitations. Users often encounter issues such as poor road conditions and unforeseen obstacles, to which ordinary canes cannot provide accurate responses. This greatly impacts the safety of blind pedestrians. Our smart ultrasonic stick for blind people resolves this problem. It consists of a wearable stick equipped with ultrasonic sensors for detecting obstacles. A buzz-kal gives alerts according to the direction of an obstacle from the user. An Arduino NANO central processing unit (CPU) processes information from the sensor about obstacle distance, according to the specific coding we use, and transmits the output through the buzzer. The stick operates through a central power supply that distributes power to the different components. The sensor, placed between the top bar and the bridge in the smart stick, connects to the central unit using single-strand copper wires. We opted for ultrasonic sensors due to their low energy consumption over long propagation distances. This makes them ideal for measuring long lengths. Furthermore, the sensors adapt well to various harsh conditions such as darkness, dust, smoke, electromagnetic interference, and toxicity, proving their wide range of applications.
