Design and realization sensorial system on detection obstacle

This article deals with a miniature infrared and ultrasonic sensors to avoid collisions with obstacles of mobile devices. At the beginning of the work I focused on the infrared sensor. Infrared sensor is used to detect over short distances. The impact of the infrared sensor is several tens of centimetres. It was therefore necessary to propose the ultrasonic sensor to make sure the shooting at greater distances. The key advantages of these sensors is a simple structure, high accuracy, possibility of integration, and their relatively low price compared to commercial prices. Sensors and their properties.
