INTRODUCTION

The project is microcontroller based range finder through distance

sensor. Our project is based on the PIC Microcontroller now the question

is why we are using PIC as it has the most important feature of inbuilt

ADC, stands for Analog To Digital Converter.

The distance measured depends on the quality of the sensor. In our

project we are measuring the distance up to 36 cm.

The distance sensor can sense the distance of the object and produce

an analog quantity corresponding to the distance of the object and using

this quantity the range of the object is calculated .Here a PIC

microcontroller is used to sense this analog quantity and process it to

indicate the range of the object .

AIM OF THE PROJECT

The AIM of the project is to design a system

which can detect any object and find the

range of that object so that presence of it can

be detected .It would be helpful where it is

difficult for us to see.In case where there is

lack of vision or the visibility is not clear this

project would be very helpful there .

WORKING OF THE PROJECT

In this project we are working on PIC microcontroller which has inbuiltADC so it can sense an analog signal at its input and convert it into a digital

signal at its output. A distance sensor is connected to the pin of the PIC

microcontroller which can detect the presence of any object .As soon as it

sense the presence of object and its distance,information of the distance

it produces is of analog in nature which is forwarded to the PIC controller,it process analog signal according to the software loaded in it ,and display

it on the FND display and run the buzzer for informing a person that the

object is sensed .

The distance measured depends on the quality of the sensor.

In our project we are measuring the distance up to 36 cm.

CONCLUSION

This system can be used in different

industries and can proved to be very helpful in

identifying different items very accurately, the

only drawback of our system is that it cannot

be used for identifying the location.

In order to overcome this drawback we can

use GPS system to locate the co-ordinates theitems position.
