If there is no gap between two persons, then Microcontroller will sense that auromatic 1 person has entered into room. Do you have any question or any feedback about this project? Hi bhakti2, yes we can connect DC motor. No, this project can not work for multiple rooms simultaneously. Please refer to description and image given in the project details section above. I have a doubt.

I too microcontrolker this project. Hi Mohamad Nazreen, you can get this project in 7 working days. And this sensor does not recognize the number of person.

Sir is any sensor to detect light brightness and then on light at day timeor keep it off At day time with blood sensor and temperature sensor Can u give any comment about this. Applications of the project: Output of IC is given to the Darlington circuit. Can we get volt as output of the relay because here in Canada we have lights works in volt?


IR sensor are low cost and can not be false triggered. Since relay is used, you can connect an AC bulb or DC bulb as per your requirement. 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.

Do you have any specific reason? And if you want to operate this project on regulated DC supply then you can remove transformer and you can directly give 9 volts supply. Although there are different functions for LCD microcontrolldr person counter modules, but they are combined in a single program. Human efforts to count the number of person is eliminated.

So the relay light will be turned on when there is darkness. You have to install one project for each room. This is to give some presentations on projector or big screens. If a person enters the room then first receiver will cut and then second receiver will cut. Swap any object like mobile or your fingers not single finger in front of those sensors.

Automatic Room light Controller & Person Counter

Bidirectional Visitor counter section — It is bidirectional because we have used 2 sensors on a single door. 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. Bidirectional person counter project can be used in Cinema halls, multiplex, malls as well as in temples to count the number of person entering inside. Hi Raj, yes there will be a program HEX code downloaded into the controller.


In this project we have set the limit to 15 for demo purpose. This is the CPU central processing unit of our project. Suppose a seminar hall has seating capacity of then only people should be allowed inside room. We have provided ocntroller the advanced version of this project. TV, radio set, fun, flat iron, computers, chargers.

Automatic Room light Controller with Visitor Counter

There should be some time delay at-least half seconds delay between 2 persons Question: It is used to increase the current gain. Actually we already have 2 such projects. One of these 2 pins is connected to the Normally open terminal of the Relay which is also known as NO contact.

Sir i am guhan doing my BE.
