Learn the working of PIR here: Problem is that the Red LED connected to the IR receiver is always active always turned on and only blinks when I try to cut the infrared beam from the arrangement of IR transmitter and receiver which you sent me.

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 autoomatic, i selected this project as final year project. Resistor values are clearly mentioned in the Circuit Diagram. Here is two functions for enter and exit.

The total number of persons inside the room is also displayed on the LCD display. Also we can provide a time lag between switching off devices. It is central processing unit for the project. This is one of the best sensor based projects for final year. So when the IR rays are interrupted by any person then Microcontroller will receive a high pulse from the IR receiver.

An IR sensor can measure the heat of an object as well as detects the motion. Sir, how will the code change accordingly if I use microcontroller in place of aurdino board.


Automatic Room light Controller with Visitor Counter

Transistor is used to drive the relay because arduino does not supply enough voltage and current to drive relay. Hi Its a nice simple yet effective project I face troubles in relay connections i used a 5-pin,5v relay It would be of great help if you could mail me relay connections with the pin counher and reqd. And if any person leaves the room then second receiver will cut and then first receiver will cut. I really need your help to complete my final year project.

Yes, we can do that. Project will display actual number of persons inside the room.

Automatic Room light Controller & Person Counter

Can u suggest any other sensors which will detect only human being or human body? Can u guys make a tutorial to detect room entry alert system using alarm with clear explanation??? This site uses Visitog to reduce spam. In this project can we use any sensor other than TSOP?

In the website you have given a chart showing the placement of the circuit, in that picture the transmitter1 and receiver2 is on one side of the frame and vice versa.

We can either use AC fan or DC fan as well.

It has Wide Supply Ranges. What are the ways of avoiding false triggering? I have the same problems. The whole system can be fabricated as economic commercial hardware package.

It can also be used at gates of parking areas and other public places. Hi Sir, I found this project interesting although the what will happen if the two persons enter and exit at the same time then there will be a collision between the entry and exit.


The receiver has a RX at the front end. LM has inbuilt two low noise Op-amp. However for this we need to modify the circuit.


We think you have liked this presentation. We will reply you total cost including shipping charges. Here we can use sensor and can know present number of persons.

This function is implemented using wit pair of Infrared sensors. I also had some soldering issues which were resolved using continuity checks performed on the hardware. The microcontroller does the above job. IR sensor are low cost and can not be false triggered.


Below is the diagrammatic representation on how the two sensors should be placed on the door frame. Sir my project name is automatic room light control using ir sensor I using ardiuno uno r3 circuit board then I don’t know this programming please help me and give the programming. This circuit proves to be helpful. In this project we have set the limit to 15 for bidirectionall purpose. By combining a versatile 8-bit CPU with Flash on a roim hip, the Atmel AT89S52 is a powerful Microcontroller, which provides a highly flexible and cost effective solution bidirectiohal many embedded control applications.

Hi Naveen, Two transmitters should have sufficient distance between each other so that they will not interfere with each other. Hi Rajkumar, the microcontroller IC is already programmed.
