Since this project uses 2 infrared sensors, it can be used as Bidirectional person counter as well. Sir, Autojatic I use Cunter collision sensor in this project?


You have to install one project for each room. Hi Raj, yes there will be a program HEX code downloaded into the controller. Hi im from malaysia, if i order this project, when can i get it?

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. How to check if IR sensor is working or not?

Can this model hypothetically sense whether a person is going in or out of a room? But the IR receiver is not giving active low output.

Automatic Room light Controller with Visitor Counter (AT89S52)

However it is not possible to add blood sensor in this project. Extra shipping charges are applicable for delivery out of India. Actually we already have 2 such projects. More information about text formats. The various functions of Microcontroller are like: If the second sensor is not interrupted within 5 seconds then the waiting period gets over and action is cancelled.


In such places the power consumption of project is negligible as compare to the electricity wastage. Similar or Related Projects: Light sensor — LDR will detect the sunlight in the room or we can say LDR is used to detect daytime If there is enough sunlight in the room which means it is a daytime then the relay will not be turned on even if the person conrroller is greater than zero. Automtaic should be some time delay aytomatic half seconds delay between 2 persons Question: What are the ways of avoiding false triggering?

Applications of the project: Output of IC is given to the Darlington circuit. And counter will decrement if second sensor is interuppted first and then first sensor.

And in case of person leaving the room, sensor sequence will be as below: We have used 2 infrared sensors and these are installed on door.

Although there are different functions for LCD and person counter modules, but they are combined in a single program. Can u suggest any other sensors which will detect only human being or human body?

If you use LDR as a sensor then it can be easily triggered by sunlight or any other sources of light.

Display — Microcontroller sends the person count to LCD so that the person operating this project should read the number of persons inside the room.



If the circuit is still not working properly then try varying the potentiometer, reduce the resistance. Since Microcontroller can not turn on relay directly, we have used a Relay driver circuit.

Can we get volt as output of the relay because here in Canada we have lights works in volt? And following are the important modules in this project: Concerning pets in the room, are they likely to trigger the system? Counter will increment if first sensor is interrupted first and then second sensor.

Automatic Room light Controller & Person Counter

Sir, I am from Bangladesh, we have a problem with electricity in our country. Then Microcontroller will increment the count. Because when there is nobody inside the room visior lights are automatically turned off. Once the count is non-zero, the room light is turned on using relay.

Relay does not give any voltage output. So in a real case scenario, if someone stays infront of the door for sometime, either the count will go continuously up or down. But 1 more thing, if your pets jump 4 feet from ground then this will trigger the sensor: Block Diagram of the project:
