Bidirectional Visitor Counter

Bidirectional Visitor Counter using Arduino

A bidirectional visitor counter using Arduino may be a reliable circuit that takes over the task of counting variety of Persons/Visitors within the Room very accurately. if somebody enters into the space then the Counter is incremented by one and also leaves it might be incremented.

MATERIALS REQUIRED:

• Arduino
• IR Module
• 16*2 LED
• 5V Relay
• Resistor(1K,220 ohm)
• Breadboard
• Jumper Wires

The total number of persons inside the space is Shows on the 16X2 LCD module. The microcontroller does the work it receives the signals from the sensors, and this signals operated under the control of software which is stored in EPROM of Arduino.

There are two IR Modules are used. first, one are often wont to count the amount of persons entering a hall within the up mode at the doorway gate. and therefore the other can count the amount of persons leaving the hall by decrementing the count at the exit gate.

In this Project will helps to Wastage of electricity. In our home, school, colleges or industry we see that fan and lighting point are kept on albeit there's nobody within the room. This happens thanks to negligence or because we forgot to show lights off or we are during a hurry.

To avoid all such situations this project called “Automatic light controller with visitor counter” is meant . This project has two functions, the primary one is understood as “ Visitor counter” and therefore the other is understood as “Automatic light controller”.

The main concept behind this project is understood as “Visitor counter System” which measures the amount of persons entering any room sort of a room , hotel rooms, seminar hall. This project is implemented using the IR sensor module with Arduino. Whereas Arduino receives the signals from the sensors, and this signal is operated under the control of software which is stored within the EPROM of the Microcontroller.

Bidirectional Visitor Counter using Arduino may be a simple hobby project which may do any of them without an Electronics or Programming Knowledge

Code:

#include<LiquidCrystal.h>

LiquidCrystal lcd(13,12,11,10,9,8);

#define in 14 // Analog pin A0 has a IR Module attached to it.

#define out 15 // Analog pin A1 has a IR Module attached to it.

#define relay 2 // Digital pin D2 has a Relay attached to it.

int count=0;

void IN()

{

    count++; // increment the value

    lcd.clear();

    lcd.print("Person In Room:");

    lcd.setCursor(0,1);

    lcd.print(count);

    delay(1000);

}

void OUT()

{

  count--; // increment the value

    lcd.clear(); // Clear the LCD Value

    lcd.print("Person In Room:");

    lcd.setCursor(0,1); // set the cursor positon

    lcd.print(count); // Display count value

    delay(1000);

}

void setup()

{

  lcd.begin(16,2);

  lcd.print("Visitor Counter");

  delay(2000);

  pinMode(in, INPUT); // Assign the IR is Input

  pinMode(out, INPUT);Assign the IR is Input

  pinMode(relay, OUTPUT); Assign the Relay is output

  lcd.clear();

  lcd.print("Person In Room:");

  lcd.setCursor(0,1);

  lcd.print(count);

}

void loop()

{  

   if(digitalRead(in))

  IN();

  if(digitalRead(out))

  OUT();

    if(count<=0)

  {

    lcd.clear();

    digitalWrite(relay, LOW); // relay is in ON conditon

    lcd.clear();

    lcd.print("Nobody In Room");

    lcd.setCursor(0,1);

    lcd.print("Light Is Off");

    delay(200);

  }

    else

    digitalWrite(relay, HIGH); // relay is OFF condition  

}
