The objectives of this research were (1) to design and create an obstacle warning circuit device for the visually impaired and hearing-impaired elderly; (2) to determine the effectiveness of the obstacle warning circuit device for the visually impaired elderly. sight and hearing-impaired Effectiveness of obstacle warning devices for visually and hearing-impaired elderly people. Using the principle of reflection of infrared waves to detect obstacles, this circuit can detect obstacles in front. And at different levels, the distance of obstacles can be adjusted to no more than 2 meters if obstacles are found. The circuit will send a warning signal in the form of sound from a buzzer speaker (Buzzer) and a blinking LED light that can be seen as well. From testing the effectiveness of the obstacle warning circuit for the visually and hearing-impaired elderly. The performance of the cane is 93.67% of the actual system that has been set. Objective (3) is to survey the satisfaction of the testers using the obstacle warning circuit device for the visually impaired and hearing-impaired elderly. The test results showed satisfaction among elderly people with visual impairments. and overall hearing impairment is at a high level has an average of 4.31
