摘要：Blindness is a lacking state of visual perception due to neurological or physiological factors. Partial blindness represents the integration lack in the optic nerve growth or the eye visual center. The total blindness is defined as the full absence of light visual perception. The deaf and blind persons are frequently suffering at mostly exercising of basic things in daily life. This suffering makes lives almost at risk during traveling through obstacles, due to necessary equipment lack in my country that provides them an assistance state to avoid or cross over the risk. For this reason, the idea of research was come to design and manufacturing ultrasonic sensor. The proposed work contains friendly user, cheap, and simple alarm system that is implemented and designed support the mobility of both visually impaired and blind people in a specific area. This work includes wearable equipment that consists of cummerbund for helping the blind person in the way navigation safely alone by avoiding encountered obstacles whether mobile or fixed to prevent any possible hard accident. The main system component is the ultrasonic wireless sensor which is used for scanning the predetermined around area of the blind by emitting-reflecting waves. The echo or reflected signals are received by Arduino microcontroller which are coming from barrier objects. The issued commands are carried out by the microcontroller to communicate the status of device back or given appliance to the vibration device. In this project a sensor is used to detect around obstacles within 150 cm of designed range. It can change the distance by simply changing the variable resistance button to avoid the blind person through the vibration when there is a risk.
