I have faced the same problem with you. 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, It can also be used at gates of parking areas and other public places. I am facing the same problem on my project. Check this for IR sensor building: Sir, Can I use IR collision sensor in this project? And the value shouldn’t go negative as there is condition for that automatic room light controller with bidirectional visitor counter the code, please check.

Any IR sensor module should work here, please set the proper sensitivity of sensor by rotating the potentiometer on it. Hello Sir, Is there anyway to prevent the counter from moving up or down when i place my hand infront of 1 of the sensors constantly? There is one IR pair automatic room light controller with bidirectional visitor counter 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.

Will u please send the altered code.

Please tell me how to change program according to this above mentioned. Please read all the above Comments before asking any question, your questions are already answered.

I don’t have a lot of programming experience, and I am struggling with fixing the code.

And counting is displayed on a 16×2 LCD through the automatic room light controller with bidirectional visitor counter.

Here in this circuit we have used two comparators for two sensors. This project is divided in four parts: I have the same bidlrectional. Resistor values are clearly mentioned in the Circuit Diagram. You must have interchanged the NC and NO, please check. Learn the working of PIR here: Web page addresses and e-mail addresses turn into links automatically.

Can we have a circut diagram using this type of module? Try understanding the ahtomatic, and change it accordingly. Can you please send me the altered program which worked for you. Sir plz send me correct code ,no ic arduino uno. If you look at the circuit diagram, it already has v AC bulb connected through the Relay. And also check for zero condition.

That’s how it is supposed to work. If ever i leave my hand infront of 1 of my sensors, the count eitheir goes up or down.

There are numerous tutorial on the web. Then comparator compares both voltages and generates a digital signal at output. Often we see visitor counters at stadium, mall, offices, class rooms etc.

Leave this field blank.

Do not keep any unnecessary moving things in front of IR sensors. Please check your circuit connections and code twice.

First we have included library for LCD and defined pin for the same. 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. Can you pls send a circuit diagram? How can i connect Volt AC bulb to it.
