I have the same problems.

What can be the problem? Yes, we can implement this. And this sensor does not recognize the number of person. Im face with the same issue. Also if at all one wants to know the number of people present in room so as not to have congestion. Since this project does the automatic person counting with the help of two sensors installed on door frame. This is an bus—so many shields can be stacked and used in parallel.

Sir, is there any kind of programming also involved with the micro-controller 89s51 in this project? The total number of persons inside the room is also displayed on the seven segment displays.

The total number of persons inside the room is also V and Dual Supplies: Introduction Of Project 1. Still the desired output was not obtained and so troubleshooting was done. Please tell me how to change program according to this above mentioned.

Your email address will not be published. And following are the important modules in this project:. Check this for IR sensor building: One relay driver circuit we are using to control the light. And is the microcontroller need to be programmed?

It contropler also be used at gates of parking areas and other public places. Please check bidirectionaal circuit connections and code twice. The IC in the gidirectional side is to generate 36 kHz square wave. Yes, we can ship this project to Malaysia.

Wireless connectivity can be added to system, by controlling the Wi-Fi modules. Hi mbavu, yes this is feasible.

The bidirectioal may be triggered and reset on falling waveforms, and the output circuit can source or sink up to mA or drive TTL circuits. The LTS is a 0.

Automatic Room light Controller with Visitor Counter

There should be only 1 person entering or leaving. Any IR sensor module should work here, please set the proper sensitivity of sensor by rotating the potentiometer on it. And also check for zero condition. Suppose a seminar hall has seating capacity of then only people should be allowed inside room. When the number of persons inside the room is zero, lights inside the room are turned off using a relay interface.

Output signal from AT89S52 is given to the base of the transistor, which we are further energizing the particular relay. I am current doing my final year project in BEng Electronic Engineering. 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. Actually we already have 2 such projects.


We have used Infra-Red transmitters. The main intention of this block is to sense the person. But i have a question. Also IR rays are not affected by any other sources. In this block mainly we are using the transistor and the relays. Extra shipping charges are applicable for delivery out of India.


Hi papun, yes we can connect these devices to a counher relay. In other cases, where sunlight is enough and lights are not required in day time, we can turn off the project so it will not function. This section will display the counted number of people and light status when no one will in the room. Is the programme is alredy dumped by you? The light will be only switched Visitod until all the persons in the room go out. Hi kashafmicrocontroller just reads the output signal from IR receiver sensor.

Does it works for same entry ,exit door.???? Will u please send the altered code. Hello Sir, Is there anyway to prevent the counter from moving up or down when i place my hand infront of 1 aitomatic the sensors constantly? Would you share your altered code with me? It is used to increase the current gain.
