Since Microcontroller can not turn on relay directly, we have used at89z52 Relay driver circuit. Output of IC is given to the Darlington circuit. If yes then are programming for counters and for LCD Displaying separately? If you use LDR as a sensor then it can be easily triggered by sunlight or any other sources of light. 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.

How to overcome this situation? Concerning pets in the room, are they likely to trigger the system? Then Microcontroller increments or decrements the counter. 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 vontroller which means it is a daytime then the relay will not be turned on even if the person count ligut greater than zero.

It is used to increase the current gain. Enhancement added to this project: It is central processing unit for the project.

When the number of persons inside the room is zero, lights inside the room are turned off using a relay interface. We can send this data to a remote location using mobile or internet. I have a doubt. Yes, we can ship this project to Malaysia. And if any person leaves the room then second receiver will cut and then first receiver will cut. We have used Infra-Red transmitters.

Kaya ap ya bna sakty hn?? This is to give some presentations on projector or big screens. And room light is turned off once the count becomes zero. These details are mentioned in the project report.

Im face with the same issue. Actually we already have vistor such projects. But please send details of your customized requirement to our email id.
