Arduino is a microcontroller based physical computing platform. Rasberry pie is microprocessor based single-board computer (SBC).

Introduction

IR Proximity Sensor:

The IR Proximity sensor is to perceiver the occurrence of any object without beginning in contact with with-it.
It senses the accurate distance of a particular object.
It will emit electromagnetic radiation.

Figure1: IR sensor

IR LED Emitter:

It will also emit light.
When the object occurs it will produce light

Figure 2: IR Emitter

Parts Of List:

Arduino UNO
IR Led Receiver
IR Emitter
Bread Board
Hookup Wires
Buzzer

Connection

Step 1: Fix the IR Receiver on the breadboard.

Step 2: Fix the IR Emitter 4 on the breadboard.

Connection Of Bread Board To Arduino:

Step 1: Take the IR Receiver Gnd pin to the Analog pin A0, then Vcc to the Digital pin 02.

Step 2: Take the IR Emitter to connect the Gnd pins commonly then Vcc pins commonly.

Step 3: Connect to the Arduino UNO board.

Step 4: Fix the buzzer in the Arduino board.

Program:

int IRpin = A0; // IR photodiode on analog pin A0
int IRemitter = 2; // IR emitter LED on digital pin 2
int ambientIR; // variable to store the IR coming from the ambient
int obstacleIR; // variable to store the IR coming from the object
int value[10]; // variable to store the IR values
int distance; // variable that will tell if there is an obstacle or not
void setup()
{
Serial.begin(9600); // initializing Serial monitor
pinMode(IRemitter, OUTPUT); // IR emitter LED on digital pin 2
digitalWrite(IRemitter, LOW); // setup IR LED as off
pinMode(11, OUTPUT); // buzzer in digital pin 11
}
void loop()
{
distance = readIR(5); // calling the function that will read the distance and passing the "accuracy" to it
Serial.println(distance); // writing the read value on Serial monitor
// buzzer(); // uncomment to activate the buzzer function
}
int readIR(int times)
{
for (int x = 0; x < times; x++)
{
digitalWrite(IRemitter, LOW); //turning the IR LEDs off to read the IR coming from the ambient
delay(1); // minimum delay necessary to read values
ambientIR = analogRead(IRpin); // storing IR coming from the ambient
digitalWrite(IRemitter, HIGH); //turning the IR LEDs on to read the IR coming from the obstacle
delay(1); // minimum delay necessary to read values
obstacleIR = analogRead(IRpin); // storing IR coming from the obstacle
value[x] = ambientIR - obstacleIR; // calculating changes in IR values and storing it for future average
}
for (int x = 0; x < times; x++) { // calculating the average based on the "accuracy"
distance += value[x];
}
return (distance / times); // return the final value
}
void buzzer()
{
if (distance > 1)
{
if (distance > 100)
{
digitalWrite(11, HIGH);
} else
{
digitalWrite(11, HIGH);
delay(150 - distance); // adjust this value for your convenience
digitalWrite(11, LOW);
delay(150 - distance); // adjust this value for your convenience
}
} else
{
digitalWrite(11, LOW);
}
}

Explanation:

In this article it can be used to detect the object at a particular distance.
It can display the distance of an object in the Serial Monitor accurately.
If they have the signal of the object it will produce the sound when it reaches the signal.
