But please send details of your customized requirement to our email id. What can be the problem? Applications of the project: And in a reverse way, person count will be decremented if somebody leaves the room. So i think some concept and when i take some notes related to my project through internet i have found yours…. It should be connected to second terminal of variable resistor RV. Hi I am Really looking forward to purchase this project… but i am not getting how does both the Tx n Rx will count the person entering and leaving the room with same door for entrance and exit….

Human efforts to count the number of person is eliminated. Use a potentiometer to adjust the frequency of transmitter circuit.

Automatic Room light Controller with Visitor Counter (AT89S52)

Can u guys make a tutorial to detect room entry alert system using alarm with clear explanation??? Im face with the same issue. Output of IC is given to the Darlington circuit.

And this sensor does not recognize the number of person. We have to take precaution that the IR rays of first transmitter should fall only on first IR receiver and not on second receiver. We have used 12 volt relay. And if any person leaves the room then second receiver will cut and then first receiver will cut.

Can we get cointer as output of the relay because here in Canada we have lights works in volt? I dont like to buy some projects in some other project center.

We can even add Temperature sensor as per your requirement. Then Microcontroller decrements the count. Project will display actual number of persons inside the room.

Sat Apr 21 Relay at98s52 section consist a BC transistor and a controllee volt relay for controlling the light bulb. Can you provide a approx. Buzzer will be turned on when maximum limit of person count has reached. Is the programme is alredy dumped by you? Hi Roshan, yes 89s51 microcontroller programming is involved in this project. Yes, we can ship this project to Malaysia. Does it works for same entry ,exit door.????

This happens due to negligence or because we forgot to turn lights off or when we are in hurry. We have not used any separate Conter for the counting. LCD display placed outside the room displays this value of person count. And if there insufficient sunlight in the room then only the relay will be turned on so as to turn on the bulb. We have used 2 infrared sensors and these are installed on door.

The various functions of Microcontroller are like:.

I have checked all the circuitry, its fine. Relay acts as a switch.

Do you have any question or any feedback about this project? What are the advantages?

The reason behind choosing IR LED is, infrared beams are not visible to human eyes and they are not easily triggered by other sources in the environment. The various qt89s52 of Microcontroller are like: But it is less compare the the power consumption of Lights and Fans. The microcontroller does the function of Reading the digital input from two infrared receivers and calculates the number of persons from them.

When person enters room then sensor sequence will be automztic below: Can u suggest any other sensors which will detect only human being or human body?
