Project Area of Specialization

Computer Science

Project Summary

Now a days everyone using phone,and sometimes they are so lost in their phones that they don't pay attention to their surrounding which cause number of accidents.For example when they walking on the road, talking/texting on phone or when they making tiktoks they doesn't pay attention to their surroundings.They are so immersed in their tiktok they dont know whether car is coming from behind or their is some open holes in front of them .

So to avoid sudden accidents,we want to create an app which helps them to protect their self or reduces accidents.This app can vibrate or making voice if any object comes on their way as well as provide the right direction.

Due to this,the chances of road accidents will be reduce.

Project Objectives

The objectives of this project is to develop an app,which helps the users to avoid unfortunate mishaps while walking on the road.

Project Implementation Method

I. INTRODUCTION

With the increasing demand for autonomous projects, the use of sensors is increasing. Sensors are sophisticated devices that convert the physical parameter into a signal which can be measured electrically.

It can be used in android apps to detect obstacles in their way

It can also perceive its own environment and through programming can get the output it desires. Out of these, the motion detectors are based on the Infra-Red, Ultrasonic, and Microwave / radar technology.Ultrasonic sensors can be used to solve even the most complex tasks involving object detection or level measurement with millimeter precision, because their measuring method works reliably under almost all conditions. Infrared sensors too, find applications in many everyday products. Their low power requirements, their simple circuitry and their portable features make them desirable.

CRITERIA TO CHOOSE A SENSOR

With the large number of sensors available in the market, it is necessary to choose the right sensor. There are certain features which have to be considered when we choose a sensor: Accuracy, Environmental condition, Range, Calibration, Resolution, Cost and Repeatability. In our project we have made an app for which can notify users from obstacle.

For this we need to select a suitable sensor. Therefore, we first carried out a study of the following ultrasonic sensors. Features of Ultrasonic Sensors

No other measuring method can be successfully put to use on such a wide scale and in so many different applications.

1) The device is extremely robust, making it suitable for even the toughest conditions.

2) The sensor surface cleans itself through vibration, making the sensor insensitive to dirt.

3) The physical principle—the propagation of sound—works, with a few exceptions, in practically any environment.

4) Ultrasonic sensors have proven their reliability and endurance in virtually all industrial sectors

I. WORKING PRINCIPLE OF AN ULTRASONIC SENSOR The ultrasonic sensor transmits sound waves and receives sound reflected from an object. When ultrasonic waves are incident on an object, diffused reflection of the energy takes place over a wide solid angle which might be as high as 180 degrees. Thus some fraction of the incident energy is reflected back to the transducer in the form of echoes. If the object is very close to the sensor, the sound waves returns quickly, but if the object is far away from the sensor, the sound waves takes longer to return. But if objects are too far away from the sensor, the signal takes so long to come back (or is very weak when it comes back) that the receiver cannot detect it.

Benefits of the Project

It will reduce accidents on the roads.
Mobiles users will be notify if any obstacle came on their path.
The main benefit is that it can be used by everyone,it will protect them from any sudden mishap.
