Can you pls send a circuit diagram?

Arduino read these signals and send commands to relay driver circuit to drive the relay for light bulb controlling. Im face with the same issue. Hi Its a nice simple yet effective project I face troubles in relay connections i used a 5-pin,5v relay It would be of great automatic room light controller with bidirectional visitor counter if you could mail me relay connections with the pin specs and reqd.

If ever i leave my hand infront of 1 of my sensors, the count eitheir goes up or down. Leave this field blank. I am current doing my final year project in BEng Electronic Engineering.

I automatic room light controller with bidirectional visitor counter need your help to complete my final year project. You can easily send this data to Computer, by using some code Serial. I had tried to modify the code and still cannot get couunter correctly. Resistor values are clearly mentioned in the Circuit Diagram.


Learn the working of PIR here: 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.

LM is livht as comparator. Please see our Privacy Policy for more details. Check this for IR sensor building: I am doing a solar automatic lighting control system for a house.

Otherwise check the automatic room light controller with bidirectional visitor counter and code once again. Here is two functions for enter and exit. Hello everyone, i selected this project as final year project.

IR Sensor Module Circuit. Sir pls send code. Please read all the above Comments before asking any question, your questions are already answered. Good thought, for this you can either increase the Delay in code or add some condition to avoid this, like only counher 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.

This project is already counting multiple persons, please check the Video. LCD is connected in 4 bit mode. I checked my hardware and the wiring. 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. BUT, when i finished mounting the circuit, the lcd count goes on constantly 0, -1,0,-1,0, I have the same problems. How can I use the counted automatic room light controller with bidirectional visitor counter to be sent to the serial out pin that to be used by a computer?

LM has inbuilt two low noise Op-amp. Also read all the above comments, solution has already been suggested. Display section contains a 16×2 LCD.

The code given is full and complete, please automatic room light controller with bidirectional visitor counter through the above comments, some people modified the code accordingly and you can also modify the code according to your need.

Web page addresses and e-mail addresses turn into links automatically. Is there anyway to prevent the counter from moving up or down when i place my hand infront of 1 of the sensors constantly?

Sir, how will the code change accordingly if I automatiic microcontroller cnotroller place of aurdino board.

So in a real case scenario, if someone stays infront of the door for sometime, either the count will go continuously up or down. Can we have a circut diagram using this type of module?

Then given bidirecttional to input output pin and initialized LCD in setup loop. Thank you in advance and best regards.

Here in this circuit we have used two comparators for two sensors. Try around some codes and share with us.
