Introduction: Infrared Light Switch

Hello friends of Instructables. I am here again. The project that I bring that is more useful for the lazy.
Imagine you're lying in your bed, it's cold and you're too lazy to get up from his bed to go turn on the light of your room. Then the same bed, you pick up the remote control for your TV and connect the lamp from your room and also off with the same control. Not a good design and interesting?
This is my project! Turn on and off the lamp in his room so many appliances in your home. The project essay around the photo down there ...

Step 1: Parts

1 CI PHSC-38 (or TSOP 1738)
1 CI 4017
1 Transistor BC 558
1 Transistor BC 548
1 Relay 5V 100 mA
1 Diode 1N4007
1 red LED
1 green LED
1 Capacitor 100uF 16 V electrolytic
2 resistors 1k - 1 / 8 W
2 resistors 330 to 1 / 8 W
1 resistor 100k - 1 / 8 W
1 Resistor 100 - 1 / 8 W
1 resistor 220k - 1 / 8 W

Step 2: Schematic, Adjustments, the PCB and Finish

In the original circuit is used the sensor TSOP 1738. I used the sensor that I had at hand, the PHSC-38. The site where I got the circuit did not have the PCB, so I used the program PCB Wizard to make the PCB.

The PCB is easy to make, and if you want to use the sensor TSOP 1738, you must modify the paths in the sensor. The board, which has a rectangle, over there is a place to cut, a tearing of the plate to make a network isolation and high current circuit, so to avoid interference.
Sorry, but I don't have pictures of assembly.
After you build your circuit, test and deploy it wherever you want. The circuit works with any remote control (often within the 38Khz). I hope everything goes right in your assembly. Until next. bye!

What if no 5v relay, I have only 12v relay

What was your total cost of this project

author
Nemweb (author)anandrocks2015-05-11

Sorry, I can't remeber

author
Nemweb (author)anandrocks2015-05-11

But I'm sure that it wasn't expensive.

kashifk1 (author)2014-12-25

ASSALAM -O-ALAIKUM, what is its range of working can you tell me. i will be waiting for your response.

author
Nemweb (author)kashifk12014-12-29

Something about 10 meters or even more. Depends of your IR light source and daylight.

i cannot find TSOP 1738 in my country.... can i use pic26043sm instead???

author
Nemweb (author)ibrahimazam112014-08-26

Don't appear to have any problem with it. Probably usable.

author
hikram (author)2014-06-29

remote (of good range) for this receiver ?

author
Nemweb (author)hikram2014-06-29

it is designed to use standard TV remote control or any other that has a 38KHz signal.

author
hikram (author)2014-06-29

if we want to increase the output load, like from 100W to 200W or so ... What amendment would required in the circuit ?? please guide

author
Nemweb (author)hikram2014-06-29

Just buy a relay that fits your needs. Most common relays can handle this power.

author
imakethings (author)2009-11-04

willl it trigger the relay continuously?

author
Nemweb (author)imakethings2014-06-29

yes, it wil.

gprakash1 (author)2013-09-04

Hai friend its very usefull project, in the circuit photos you displayed only 5 resistors, in the pcb layout you displayed 6 resistors, in the requirements you say 7 resistors, please suggest me what is the exact number off resistors, and what picture I have to follow, please inform me to my mail id friend, , gowthamprakash15@gmail.com

author
Nemweb (author)gprakash12013-09-04

Follow the PCB. I add one resistor to the first transistor to don't left the signal floating. I may made some mistake counting then.

author
syedj94 (author)2013-08-26

is it possible to try this on breadboard first?

author
Nemweb (author)syedj942013-08-28

Yes! Of course you can. Just pay attention to the relay: it may not fit on breadbord. I'll be thankfull you post your images

author
syedj94 (author)2013-08-24

Oh Ok. Then perhaps resistors might help. Thanks! :)

author
Nemweb (author)syedj942013-08-26

Re3sistors? where? and why?

author
syedj94 (author)Nemweb2013-08-26

he said more current needs to be lowered, therefore a few resistors might help... but i am not using any

author
syedj94 (author)2013-08-23

So you used a 6VDC relay too?

author
Nemweb (author)syedj942013-08-23

yes haha But is better to use the right voltage to don't raise amps on transistor, but as here it don't matter a lot, I used 6V relay without any problem.

author
syedj94 (author)2013-08-23

How about a 6VDC 10A 120V relay?

author
Nemweb (author)syedj942013-08-23

Well, it MAY work there. It worked here. (:

author
syedj94 (author)2013-08-22

can I use a 9vdc 10A 120v relay instead?

author
Nemweb (author)syedj942013-08-23

Yes, but you have to modify the circuit to power your relay. If you just put a 9V coil relay instead 5V it won´t work.

Ahad Baksh (author)2012-10-29

nice job man!!
wanna ask u the input source u using is '' 5v dc" but of what 'amp'??

capacitor C2 is of what value?
because your circuit diagram and schematic diagram having o.1uf & 100uf values of C2 respectively.

thnks :)

author
Nemweb (author)Ahad Baksh2012-10-29

The amperage will be something about 200mA, depends of your relay!
And about the cap value, you can choice. Bigger values will make that the answer be slow and better, and lower values, faster answer and more failed!
Thank you and good luck man ;D

Hi. This is a great circuit that you have posted .I've tried rebuilding it for myself .But even after using the correct parts and rechecking their values , the circuit starts on automatically as soon as I apply the power.Could you please tell me how to stop this false triggering?

author
Nemweb (author)Utsav252012-06-11

Hi. It isn't a false triggering, but it's on the circuit! Just change the ON to pin 3 and OFF to pin 2. This is normal an CD4017 start like that. My circuit also starts like that.

author
Utsav25 (author)Nemweb2012-06-11

Thank you .This change should work great for me .

OH!!! I'm 15 and i dont know anything about these things. Can you teach me smething??? PLS..... sometimes on come on iternet so send me an email and wait for my reply. Email: njrajgelani4@gmail.com Thank You very much in advance

author

I learned all this in internet, some books and trying! Google now very thing! XD

guzz0 (author)2011-08-22

hi,i used the tsop1738 sensor but i dont quite get how to make the insolation, so it keeps turning on and off on its own. can you help??

author
Nemweb (author)guzz02011-08-24

I don't know, but a several numbers of IR sensors have a solar light filter. The PHSC-38 have it.

author
Constantthinker43211 (author)2011-08-03

is this universal??? Like can i take ANY IR code?

author

You can get almost all IR code

author
Nemweb (author)2009-12-17

I don't understand your question!

author
imakethings (author)2009-11-02

can u post a schematic for IR transmitter??

author
Nemweb (author)imakethings2009-11-03

The IR transmitter is a remote control of TV, CD player and other devices.

author
imakethings (author)2009-11-02

is IC1 CD4017 is a flip flop?? will it latch the realy??

author
Nemweb (author)imakethings2009-11-03

no, the CD4017 is a counter. please view your datasheet to understand. bye.

Thanks for your ongoing contribution.
I suspect English may not be your native language so I should mention that the WARNING in your last step is unintelligible to me & maybe will utterly confuse others also.
I'd like to strongly suggest you either carefully re-word the warning or reply to this comment & explain exactly what you mean..
Please don't be offended, I think your project is well worth the effort of tidying up such detail, thanks again.

author
Nemweb (author)peterlonz2009-10-08

No matters. I'm not be offended, because I now as my English is very bad. I really thankful.
