Abstract: Presently a days the vehicles are full loaded with the security frameworks to decrease the danger of mischances. This paper concentrates on two kind of article discovery framework. As front and side item recognition frameworks. The utilization of ultrasonic sensors in security frameworks for urban movement by keeping up the safe separation between the vehicles. Versatile voyage control for urban movement focused around ultrasounds

Ultrasonic Sensor “ECHO” - Ultrasonic Distance Sensor

This "ECHO" Ultrasonic Distance Sensor from Rhydolabz is an amazing product that provides very short (2CM) to long-range (4M) detection and ranging. The sensor provides precise, stable non-contact distance measurements from 2cm to 4 meters with very high accuracy. It is in compact size, higher range and easy usability make it a handy sensor for distance measurement and mapping.

The board can easily be interfaced to microcontrollers where the triggering and measurement can be done using one I/O pin. The sensor transmits an ultrasonic wave and produces an output pulse that corresponds to the time required for the burst echo to return to the sensor. By measuring the echo pulse width, the distance to target can easily be calculated.

Under control of a host microcontroller (trigger pulse), the ECHO sensor emits a short 40 kHz (ultrasonic) wave. This burst travels through the air, hits an object and then bounces back to the sensor. The ECHO sensor provides an output pulse to the host (through its signal pin) when the echo is detected; hence the distance to the target can be measured from the width of this pulse.

Features of ECHO- Ultrasonic sensor:

• Range: 2 cm to 4

Conclusion:

Advancement in the safety of the vehicle by using the ultrasonic sensor. The ultrasonic sensor system is used for the vehicle safety that is it can be used in to detect the distance between the front vehicle and rear vehicle also it can be used in for side safety of the vehicle that the sensor system is placed on the side of the system for safety purpose. From that the vehicle safety in the urban traffic increases.
