Automatic Room light Controller with Visitor Counter

And the microcontroller is pre-programmed. Output of IC is given to the Darlington circuit. Also we can provide a time lag between switching off devices. One relay driver circuit we are using to control the light.

PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. Auto,atic button will reset the microcontroller. It is also known as a ‘one-shot’. Yes, we can implement this.


I altered the code only but left the circuitry the same Check some Home automation projects on this site from where you can get the idea of connecting relay: CD contains following things: The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory pro- grammar. When any object pass through the IR Receiver’s then the IR Rays falling on the receiver are obstructedthis obstruction is sensed by the Microcontroller.


Can we use proximity sensor module on this? Would you please be able to send your altered code? Since Microcontroller can not turn on relay directly, we have used a Relay driver circuit.

Automatic Room light Controller & Person Counter

Can u plz send the correct code. BUT, when i finished mounting the circuit, the lcd count goes on constantly 0, -1,0,-1,0, But please send details of your customized requirement to our email id. In this case it will not increment or decrement the count. And following are the important modules in this project:.

LM has inbuilt two low noise Op-amp. But when the person is leaving the room, the infrared exit operation will be activated and the counter decrements by one and the lights will turn off if nobody is in the room.

And turn off lights when the count is zero. Extra shipping charges are applicable for delivery out of India.

The various functions of Microcontroller are like: Because of this appropriate device is selected and it do its allotted function. Do you have any specific reason? Suppose a seminar hall has seating capacity of then only people should be allowed inside room.

A block diagram representing the circuit developed IV. Sir, Can I use IR collision sensor in this project? You will get all documents after purchasing aautomatic project.

Log In Sign Up. Mainly this block diagram consist of the following essential blocks. The whole system can be fabricated as economic commercial hardware package. 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.


Wireless connectivity can be added to system, by controlling the Wi-Fi modules. LCD display placed outside the room displays this value of person count. Feedback Privacy Policy Feedback. If yes then are programming for counters and for LCD Displaying separately? Sir pls send code. And that time Relay will get Voltage and triggered so light will get voltage and bidirectiohal will turn on.

Do not keep any unnecessary moving things in front of IR sensors. This circuit consists of a transistor which is used to turn on relay through Microcontroller. The light will be only switched OFF until all the persons in the room go out. There is one IR pair for Entry detection and another for Exit detection, if you keep your hand in front of both the IR pair, then the number will continuously goes up and down.

Use a potentiometer to adjust the frequency of transmitter circuit. By modifying this circuit and using two relays we can achieve a task of opening and closing the door.
