Otherwise check the circuit and code once again.

This section will display the counted number of people and light status when no one will in the room. Can you pls send a circuit diagram?

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? If ever i leave my hand infront of 1 of my sensors, the count eitheir goes up or down.

Check some Home automation projects on this site from where you can get the idea of connecting relay: Thank you in advance and best regards. I don’t have a lot of programming experience, and I am struggling with fixing the code. Would you share your altered code with me? Good thought, for this you can either increase the Delay in code or add some condition to avoid this, like only increase the count if IR sensor is switched from Off to ON state, and dont increases count if IR sensor is previously ON or continuously getting digitalRead in.


Im face with the same issue.

How can I use the counted value to be sent to the serial out pin that to be used by a computer? How can i connect Volt AC bulb to it.

Then comparator compares both voltages and generates a digital signal at output. Sir plz send me correct code ,no ic arduino uno. Please read all the above Comments before asking any question, your questions are already answered. Now will try optimize and add further components. So we added a relay driver circuit to get enough voltage and current for relay. If zero condition is true then arduino turn off the bulb by deactivating the relay through transistor.

Resistor values are clearly mentioned in the Circuit Diagram. Any IR sensor module should work here, please set the proper sensitivity of sensor by rotating the potentiometer on it. This project is already counting multiple persons, please check the Video. Can you please get me the modified code for counting the total number of persons entered in the room for a particular period.? If you look at the circuit diagram, it wkth has v AC bulb connected through the Controllr.


I have the same problems. If you pls send me. Check this Article for relay working: It can also be used at gates of parking areas and other public places. And Relay driver transistor at digital toom 2. Would you please be able to send your altered code? Rest of connections are shown in the below circuit diagram.

Quote and Order boards in minutes on https: I altered the code only but left bidirsctional circuitry the same Often we see visitor counters at stadium, mall, offices, class rooms etc. I am doing a solar automatic lighting control system for a house.

Can u plz send the correct code. Learn the working of IR sensor module here.

This counter can count people in both directions. And also check for zero condition.

This project is divided in four parts: Wth check your circuit connections and code twice. Try understanding the code, and change it accordingly. Relay driver section consist a BC transistor and a 5 volt relay for controlling the light bulb.
