IR transmitter and receiver

[ijazahmed619]

Plzz sir can u send me the circuit diagram to my id ijaz_red@yahoo.co.in

WHAT CAN BE USED INSTEAD OF 3 K

mast hai yaar....

[amaljoy333]

i have a idea . we can use this as a motion sensor. by placing transmiting part on one of door and other on the next side . when anyone block the ir led glow you can also use a buzzer .

hey plz send circuit diagrams , material required ,etc to my id ...plz iam trying to make this from long time.but i was not able to do it .......u can send this to my id either yahoo or gmail . i will give u both id .u send it in any one ..plz help me in making this..plz dont disappoint me ,,,,thanks

[sunilmanjunathv]

whats the model number of IR receiver and transmitter.... pls reply me....

[amruth111]

Can this IR Rx pickup reflected IR form the Tx.

[emadsiddiq98]

what do u do in the end ?

attach the positive of the led to the negative of the receiver which is connected to the positive of the battery . right?

but when i do that it doesn't work . i don't mean that u are wrong but could u please explain it and i bought an ir pair but the receiver is black is that fine?

sorry to disturb u but i am a beginner and quite confused!

please answer

[tehseenb10]

@emadsiddiq98

LED is attached at the output of the receiver( which is negative of receiver).Yes Black is fine is..

I noticed that the reversed bias reciever is incorrect as described in your schematic.

(unless my parts are labeled/Mfg'd differently)

I used a (radioshack) matched pair emitter and detector/transistor and I found that putting the reciever/transistor in as marked negative to negative positive to positive (forward biased) is the correct way to use the reciever, as reversed biased did not work.

[tehseenb10]

@TheTubejunky

Circuit is perfectly right. It is used by many users and it worked.

Here receiver is reversed bias. ( I use simple IR sensor pair)

The pair that you used is different.

[TheTubejunky]

@tehseenb10

I believe you are correct!

My parts are different and your circuit is correct.

Thank You for posting this video it helped me learn more then what I had known prior to watching it.

[jayr64]

where can i buy a receiver like the one you used? all the ones i find have 3 prongs all in a straight line. it appears the one you are using has only two? also, are there any specific LEDs that you are using? or just normal

[tehseenb10]

@jayr64

I used IR sensor pair and has only two prongs...

It is easily available in Electronic equipment shop..

[darktooth90]

how if i use 9v vcc. should the resistor value changed ?

[20bogart]

hi sir please send me a diagram please a diagram that seperated thanksss

[20bogart]

can i seperate it use two 9v batteryand seperate the ir led please answer and please send me a diagram

[tehseenb10]

@20bogart I think yes...as used in remote control...

but i have no ckt...

[tehseenb10]

@20bogart

I try,It works but you need little more circuitry for perfect result..

[francisroan]

thanks i made and it worked i made a video and its name is ir led and receiver

[tehseenb10]

@francisroan

Tested circuit and it works.

[palla9696]

the receiver is the IR led... right?

[tehseenb10]

@palla9696

Ya...

one for transmitter and other for receiver...

[francisroan]

nice i can add a buzzer instead of the led and use it as a bugler alarm

[tehseenb10]

@francisroan

yes u can use it in many ways..

[20bogart]

hiplease help how can i use other battery i mean not in one battery only ill use two battery........can i seperate ir to the other battery and transmitter to another battery and i will use two 12v battery what value of resistor will i use please help me

[20bogart]

hi again my friend what is the serial no# of the ir emitter and receiver please cause when i buy in the shop they dont have it and they are asking an no#of an ir help me please!!!!!

[Touseefelahi07]

Electronics magic...

[20bogart]

hi hello please send me a great ir transmitter and a remote control please an easy please sir thankss by the way i use it to on or of the ignition of my motor cycle thankzz

[tehseenb10]

@20bogart

thanks 4 the complement..and plz contact me via email.

I will try my best.

[20bogart]

@tehseenb10 hi im bogart im glad you answer please help me how to build that circuit and just a low cost only . please send me diagram thanksss god bless

[20bogart]

@tehseenb10 hi again thanks for all ah what is the name of that led transmitter and a receiver so that i can buy it to the electronic shop thankss god bless

[20bogart]

@tehseenb10 hi again thanks for all ah what is the name of that led transmitter and a receiver so that i can buy it to the electronic shop thankss god bless and what voltas didyou use?????

[tehseenb10]

@20bogart

Again thanks...

if u mail me your problem I try to solve your query correctly...

here I use Infrared Sensor (IR sensors) and 5v dc is used.

[20bogart]

@tehseenb10 hiplease help how can i use other battery i mean not in one battery only ill use two battery........can i seperate ir to the other battery and transmitter to another battery and i will use two 12v battery what value of resistor will i use please help me
