The inputs to your circuit are Q4 and Q5.
What do they do ?

Sir, that is the Infrared Sensor , type TSOP1738 .. it accept the infrared from the other circuit (transmission circuit)..
Sorry im really not good at this..
1 more thing, how can i burn the hex file into the AT89C52? what software and hardware used? i've made some research and ProLoad software can burn the file into it.. but how about the hardware? can i use the same hardware as PIC KIT?

What transmission circuit are you using ?

I assume you know that the items used in your Proteus diagram are transistors, not detectors.
Because of that, your simulation does not work.
You use MJ11015 transistors for switching the relay etc.
These are power transistors, far too big for the job.

As far as I know you can't program an AT89C52 using a PICKIT.
They are totally different families of micro.
There are many types of software and hardware you could use
search our posts and the web for the best ones for you.


Note that the AT89C52 needs a larger more expensive programmer than the AT89S52
Be sure to use the AT89S52.

Are you experienced in PIC programming ?
If so, I might be easier to change the project to use a PIC.

The original project used NE555s, as part of the detection circuit.
If you use TSOP1738s as detectors you don't need the 555s, making your
circuit much simpler.

as i said already, i pass the simulation process.. i replace the Q4 anf Q5 with the switch button for simulation..
i've made some adjustment, i change the C into S, which is AT89S52.. i running out of time, so i cancel up everything, now i planning to create the circuit SAME as the original, like the pictures below.. now my problem is to identify what type of component used at D1 and U3 for transmitting and receiving the infrared? (the IR Tx/Rx Pair). is it TSAL6200 and TSOP 1738?

and this one

If you are happy that the simulation works why change to the old version ?
I'm not sure how well the original worked (which is why it was changed).

my problem is to identify what type of component used at D1 and U3 for transmitting and receiving the infrared? (the IR Tx/Rx Pair). is it TSAL6200 and TSOP 1738?

That may be mentioned earlier in this thread.
If not I assume a TSOP 1738 will work and use any Infrared LED of the right wavelength.
Any LED with a wavelength between 900 and 1000 nanometres should be okay.

in my simulation software there is no AT89S52, so i replaced it with AT89C52.. but in REAL i'll use AT89S52 since in my country it's hard to find the AT89C52, and to burn the hex file into it also is more complicated.. i'll try my best to do this project.. but sir, what software i used to burn the hex file? i already have the USB part which is used to connect to the AT89S52..

@ Ginger92
the hardware that is used to burn is hex file that is called burner or programmer
every programmer has its own software to load hex file
you can use at89s52 as well as at89c52 that is available in your local market both are same things
what programmer you are using for burning the hex file
