Check the IR module you have built, and adjust the sensitivity of circuit. Rest of connections are shown in the below circuit ajtomatic. Check some Home automation projects on this site from where you can get the idea of connecting relay: This project is already counting multiple persons, please check the Video.

Can we have a circut diagram using this type of module? Sir, Can I use IR collision sensor in this project? Then comparator compares both voltages and generates a digital signal at output. This counter can count people in both directions. Please tell me how to burn display. I am current doing my final year project in BEng Electronic Engineering. Check this for IR sensor building: If you look at the circuit diagram, it already has v AC bulb lighg automatic room light controller with bidirectional visitor counter the Relay.

Would you share your altered code with me? Circuit Explanation There are some sections of whole visitor counter circuit that are sensor section, control section, display section and driver section.


Learn the working of IR sensor module here. Can you please send me the altered program which worked for you. And the value shouldn’t go negative as lifht is condition for that in the code, please check. Leave this field blank. More information about text formats. LM is used as comparator.

And Relay driver transistor at digital pin 2. The sensor would observe an interruption and provide an input to the controller which would run the counter increment or decrement depending on entering or exiting of the person.

bidirecfional Sir plz send me correct code ,no ic arduino uno. Then given direction to input output pin and initialized LCD in setup loop. 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.

automatic room light controller with bidirectional visitor counter 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. Here is two functions for enter and exit. I checked my hardware and the wiring. That’s how it is supposed to work. Can we use proximity sensor module on this?

Lines and paragraphs break automatically. Learn the working of PIR here: Sir can you send me all detail about this project like source code, component and etc because i want make bidirectionxl project for project last year for my college. There are numerous contdoller on the web. Display section contains a 16×2 LCD.


Hello everyone, i selected this project as final year project. All the components, circuit, code are already given in the project, please check. If ever i leave my hand infront of 1 of my sensors, conttroller count eitheir goes up or down. Can you please get me the modified code for counting the fontroller number of persons entered in the room for a particular period.?

I have faced the same problem with you. What are the values of the resistances and the pins they need to be connected? BUT, when i finished mounting the circuit, the lcd count goes on constantly 0, -1,0,-1,0, Sir, how will the code change accordingly if I use microcontroller in place of aurdino board. If you pls send me. How can i automatic room light controller with bidirectional visitor counter Volt AC bulb to it. Arduino read these signals and send commands to relay driver circuit to drive the relay for light bulb controlling.


Please help me sir. It can also be used at gates of parking areas and other public places. Im face with the same issue. Do not keep any unnecessary moving things in front of IR sensors.
