The whole system can be fabricated as economic commercial hardware package. Help Center Find new research papers in: Hi im from malaysia, if i order this project, when can i get it? Can u plz send the correct code. And in a reverse way, person count will be decremented if somebody leaves the room. Check the IR module you have built, and adjust the sensitivity of circuit.

Since Microcontroller automatix not turn on relay directly, we have used a Relay driver circuit. I have a doubt. Budirectional bhakti2, yes we can connect DC motor.

With the increase in the living standards, their specific functions.

Automatic Room light Controller & Person Counter

Enter the email address you signed up with and we’ll email you a reset link. However for this we need to modify the circuit.

The code given is full and complete, please go through the above comments, some people modified the code accordingly and you can also modify the code according to your need. We have not used any separate IC for the counting. The light will be only switched OFF until all the persons in the room go out. What are the advantages?


Counter will increment if first sensor counyer interrupted first and then second sensor. If you look at the circuit diagram, it already has v AC bulb connected through the Relay. This is done by Relay. Hi Devang b patel, we have already included Light sensor to detect daytime.


There should be some time delay at-least half seconds controllwr between 2 persons Question: One of these 2 pins is connected to the Normally open terminal of the Relay which is also known as NO contact.

Automatic Room light Controller with Visitor Counter

The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer.

Often we cunter visitor counters at stadium, mall, offices, class rooms etc. By using this sensor and its related circuit diagram we can count the persons. Which sensor will be used to differentiate between human body and animal body?

TV, radio set, fun, flat iron, computers, chargers. Countdr important aspect of the Arduino is its standard entering and exiting visitor of the auditorium or hall lkght other connectors, which let users connect the CPU board to a variety of place, where it is placed.

Can we get volt as output of the relay because here in Canada we have lights works in volt? Yes, we can ship this project to Malaysia.

Bidirectional Visitor counter section — It is bidirectional because we have used 2 sensors on a single door. Do you have any specific reason? And the third terminal of potentiometer RV is left open.

And also defined input output pin for sensors and ralay. I have a question,have you calculated how much energy is saved by implementing this project.

Depending upon the sensors interchangeable add-on modules termed shields. Digital Visitor Counter can be used in various rooms like seminar hall, conference hall where the capacity of room is limited and should not be exceeded. Yes, we can send the data to remove location via GSM modem.

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 count is greater than zero. This display should be placed outside the room. To make a controller based model to count number of persons visiting particular room and accordingly light up the room.


Also if at all one wants to know the number of people present in room so as not to have congestion. The cost of this technology is very economical. I have faced the same problem with you.

If there is no gap between two persons, then Microcontroller will sense that only 1 person has entered into room. Initially first sensor will be activated and later second sensor will be activated. Skip to main content. The RFID sensor will be placed outside the room for the Entry and the infrared sensors will be placed at side of the door for the exit operation.

This happens due to negligence or because we forgot to turn lights off or when we are in hurry. If yes then are programming for counters and for LCD Displaying separately? If you wish to download it, please recommend it to your friends in any social system. It is also known as a ‘one-shot’. Good thought, for this you can either increase the Delay in code or add some condition to avoid this, like only increase the count if IR sensor is switched from Off to ON state, and dont increases count if IR sensor is previously ON or continuously getting digitalRead in.
