Design of Smart System for Detecting Proximity of Obstacles at Acute and Obtuse Angles

The present paper describes an archetype capable to detect obstacles not only at right angle, but can also detect with acute and obtuse angles also. Along with ultrasonic sensor, servo motor is included for rotational purpose in the line-of-sight upto a wider range which makes the system smart. Optical signal mechanism is associated with the embedded system in order to indicate the proximity of the target, which can help to understand the importance of possible collision for moving object even in presence of noisy environment. Results can further be improved with association of GSM module which can enable text messaging service to establish the important of closeness between the source and obstacle.
