urs1

URS1 project is based on a sonar ranging system that is composed o two ultrasonic transducer. Its purpose is to transmit sonar signals and capture the very same transmitted signal when it is reflected back by an obstacle. The objective of the URS1 project is physically present the distance that signal traveled as to let driver aware of impending obstacle at back of car. URS1 is micro controller based system. Three audio signals in three zones generated by system. URS1 is very robust respect to environmental noises and fully satisfies the Automotive Standard and now is installed on IranKhodro product: Samand.
