Here is two functions for enter and exit. Display — Microcontroller sends the person count to LCD so that the person operating this project should read the number of persons inside the room.

Automatic Room light Controller & Person Counter

In the process of troubleshooting I found the circuit automaitc soldered and connected and hence came to conclusion that there was error in programming section which was later rectified and the desired results were obtained. And if it is interrupted then the microcontroller will increment the count and switch on the relay, if it is first time interrupted.

In this case it will not increment or decrement the count. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter is decremented by one.

Automatic Room light Controller with Visitor Counter

Often we see visitor counters at stadium, mall, offices, class rooms etc. Please email us your address in detail. Now swap object in reverse direction then the system decrements the count.

Try around some codes and share with us. Check this for IR sensor building: So conrroller think some concept and when i take some notes related to my project through internet i have found yours…. Do you have any specific reason? This happens due to negligence or because we forgot to turn lights off or when we are in hurry.


It gives basic idea of how to control the Lake. Please check your circuit connections and code twice. At the same time, the flip-flop brings the output pin 3 level to ‘high’. If you use LDR as a sensor then it can be easily triggered by sunlight or any other sources of light.

Introduction The main objective of this project is to track the sun and rotate the solar panel accordingly, to receive sunlight. Enter the email address you signed up with and we’ll email you a reset link.

The system counts both the other circuits. Yes, we can ship this project to Malaysia. Coujter Naveen, Two transmitters should have sufficient distance between each other so that they will not interfere with each other. Hi naomi debrtsion, please post your questions. I have the same problems. Automatic Room Light controller section — Microcontroller turns on the Room Light when person count is greater than or equal to one.

But the IR receiver is not giving active low output.

The output goes high when the there is an interruption and it return back to low after the time period determined by the capacitor and resistor in the circuit. Below is the diagrammatic representation on how the two sensors should be placed on the door frame Snehal Shinde Question and answers about this project: Hello sir I am a 9th standard student and was also thinking of this type of project onlyso I thought to check out that whether it is designed earlier or not this project is very helpful for me and I wanted to ask you that should i use this project to present in the science project exhibition or competition???

And following are the important modules in this project: Hi Elaine Lombog, yes we can add temperature control.



Depending upon the sensors interchangeable add-on modules termed shields. Normally the relay remains off. Single Supply is 3 V to 32 go out.

By using this sensor and its related circuit diagram we can count the persons. And in case of person leaving the room, sensor sequence will be as below: The various functions of Microcontroller are like: Log In Sign Up. The main function of this block is to provide the required amount of voltage to essential circuits. Hi khushboo thakare, we can implement computer interfacing or GSM modem interfacing with this project.

We can even add Temperature sensor as per your requirement.

This section will display the counted number of people and light status when no one will in the room. And turn off lights when the count is zero. But this project does not have PIR sensor. Diode D2 is the standard diode on a mechanical relay to prevent back EMF from damaging Q3 when the relay releases. I altered the code only but left the circuitry the same And light will be turn off. Transistor is used to drive the relay because arduino does not supply enough voltage and current to drive relay.

The AT89S52 provides the following standard features: How to differentiate two transmitter from their respective receivers? Also IR rays are not affected by any other sources. Can you please get me the modified code for counting the total number of persons entered in the room for a particular period.? Please email us your questions or write comments below.
