ELEX IDEA BLOG: Automatic Room light Controller with Visitor Counter (AT89S52)

Relay provides isolation from the Microcontroller circuit. In some specific seminar hall, conference rooms and study rooms, sunlight can not reach in daytime as well. Hi Rajkumar, the microcontroller IC is already programmed. So when person goes in 1st sensor is cut and then 2nd sensor is cut. So in a real case scenario, if someone stays infront of the door for sometime, either the count will go continuously up or down.

So if two or more person enters in room without any gap between them then it will treat as a single pulse. Can you provide a approx. Please refer to description and image given in the project details section above. And if there insufficient sunlight in the room then only the relay will be turned on so as to turn on the bulb. Please tell me how to burn display.

Automatic Room light Controller with Visitor Counter (AT89S52)

Advantage of using Infrared sensor is that IR rays are not visible to human eyes. 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.

Yes, we can do that. You have to remove transformer wires and at the same point controller can give 9 volt DC supply. Your email address will not be published. More information about text formats.

Then Microcontroller increments or decrements the counter. Sat Controllet 21 Relay driver section consist a BC transistor and a 5 volt relay for controlling the light bulb.

How does this system operates during bed time, because it is an automatic system and there has been a counted number of persons in a room already. So when the IR rays are interrupted by any person then Microcontroller will receive a high pulse from the IR receiver. Yes, your Pets can trigger rpom sensors. But this project does not have PIR sensor. Hello sir I am a 9th standard student and was qith 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 sutomatic present in the science project exhibition or competition???

Whenever th person enters then buzzer should be turned on to indicate that maximum capacity has reached. Yes, we can implement this. Use a potentiometer to adjust the frequency of transmitter circuit.

Hi mbavu, yes this is feasible. You will get all documents after purchasing the project. Hi Raj, yes there will be a program HEX counfer downloaded into the controller. Project Report in pdf format and in word format. Since Microcontroller can not turn on relay directly, we have used a Relay driver circuit. Can u guys make a tutorial to detect room entry alert system using alarm with clear explanation???

I have reviewed circuit and have 2 suggestions. Sir, I am from Bangladesh, we have a problem xt89s52 electricity in our country.

Can the IR sensors detect obstructions only, not the direction? Bidirectional Visitor counter section — It is bidirectional because we have used 2 sensors on a single fisitor. In this case it will not increment or decrement the count. What happens to the light when the number of persons increases than the limited???

Yes, this is possible. Are you using any separate counter IC for counting the persons or Microcontroller itself is configured as the counter? This function is implemented using a pair of Infrared sensors.

Hi I am Really looking forward to purchase this project… but i am not getting how does both conyroller Tx n Rx will count the person entering and leaving the room with same door for entrance and exit….

Wastage of electricity is contriller of the main problems which we are facing now-a-days. Why is it so? Sir can we increase maximum count of people upto 20 numbers 1 light should glow… Can we do it.?

We have used cobtroller which is a Microcontroller of microcontroller family. CD contains following things: Hi controlle thakare, we can implement computer interfacing or GSM modem interfacing with this project. There are 2 transmitters and 2 receivers placed in front of each other.

So it can detect the controllre but it gets difficult to understand if the person is entering in the room or leaving the room. If yes then at what point we can connect the DC supply because then we gave to skip the dc converter circuit? 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.

Do you have any question or any feedback about this project?
