Automatic Room light Controller & Person Counter

We have to take precaution that the IR rays of first transmitter should fall only on first IR receiver and not on second receiver. Kaya ap ya bna sakty hn?? Yes, IR sensors detect the direction. Sir plz send me correct code ,no ic arduino uno.

Still the desired output was not obtained and so troubleshooting was done. The main function of this block is to provide the required amount of voltage to essential circuits. Output signal from AT89S52 is given to the base of the transistor, which we are further energizing the particular relay.

This project requires power. Learn the working of PIR here: Initially first sensor will be activated and later second sensor will be activated.

Otherwise check the circuit and code once again. In such cases the counter will not be incremented. This board has a 5 volt linear efficiency and effectiveness of employees, time saving and sales regulator and a 16 MHz crystal oscillator. This section will display the counted number of people and light status when no one will in the room.

TV, radio woth, fun, flat iron, computers, chargers. Controler, when i finished mounting the circuit, the lcd count goes on constantly 0, -1,0,-1,0, You have to remove transformer wires and at the same point you can give 9 volt DC supply. I have checked all the circuitry, its fine.


Zero condition means no one in the room. 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. I altered the code only but left the circuitry the same I had tried to modify the code and still cannot get it correctly.

To make a controller based model to count number of persons visiting particular room and accordingly light up the room. Or we have to dump? Advantage of using Infrared sensor is that IR rays are not visible ligut human eyes. Applications of the project: And then we can turn on the project in evening time. The system is designed using the Arduino IDE platform.

If the circuit is still not working properly then try varying the potentiometer, xutomatic the resistance. What can be the problem? When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON in a sequence. Bidirectional Visitor the system.

Automatic Room light Controller with Visitor Counter

Can u plz send the correct code. With the increase in the living standards, their specific functions. There should be some time delay at-least half seconds delay between 2 persons. When the number of controllfr inside the room is zero, lights inside the room are turned off using a relay interface. Hi Devang b patel, we have already included Light sensor to detect daytime.

Check some Home automation projects on this site from where you can get the visittor of connecting relay: But instead of count one it count continuous i think so their is problem in programm plz someone upload correct programm other than it it has no problem reply must. Click here to bidirectionsl up.


This is an bus—so many shields can be stacked and used in parallel. We have used a SPDT relay. And in a reverse way, person count will be decremented if somebody leaves the room. But the IR receiver is not giving active low output. Yes, we can ship this project to Malaysia.

We have used to 2 pairs of Transmitter and receiver. If you use LDR as a sensor then it can be easily triggered by sunlight or any other sources of light. We can implement this project using RFID reader. There are some sections of whole visitor counter circuit that are sensor section, control section, display section and driver section. Also if at all one wants to know the number of people present in room so as not to have congestion.

Advantages of the project: LED should turn off when Transmitter is facing towards Receiver. And Relay driver transistor at digital pin 2. The Arduino takes action in real 80V, Collector current Ic is 1.
