Picture of 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 ...

What was your total cost of this project
Nemweb (author)  anandrocks3 months ago
Sorry, I can't remeber
Nemweb (author)  anandrocks3 months ago
But I'm sure that it wasn't expensive.

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

Nemweb (author)  kashifk18 months ago
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???

Nemweb (author)  ibrahimazam111 year ago

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

remote (of good range) for this receiver ?

Nemweb (author)  hikram1 year ago

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

hikram1 year ago

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

Nemweb (author)  hikram1 year ago

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

willl it trigger the relay continuously?

Nemweb (author)  imakethings1 year ago

yes, it wil.

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
Nemweb (author)  gprakash12 years ago
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.

is it possible to try this on breadboard first?
Nemweb (author)  syedj942 years ago
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
syedj942 years ago
Oh Ok. Then perhaps resistors might help. Thanks! :)
Nemweb (author)  syedj942 years ago
Re3sistors? where? and why?
syedj94 Nemweb2 years ago
he said more current needs to be lowered, therefore a few resistors might help... but i am not using any
syedj942 years ago
So you used a 6VDC relay too?
Nemweb (author)  syedj942 years ago
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.
syedj942 years ago
How about a 6VDC 10A 120V relay?
Nemweb (author)  syedj942 years ago
Well, it MAY work there. It worked here. (:
syedj942 years ago
can I use a 9vdc 10A 120v relay instead?
Nemweb (author)  syedj942 years ago
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.

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 :)
Nemweb (author)  Ahad Baksh2 years ago
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?
Nemweb (author)  Utsav253 years ago
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.
Utsav25 Nemweb3 years ago
Thank you .This change should work great for me .

 may I know your age?
Nemweb (author)  sunil sheth4 years ago
I'm 14 =)
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
Nemweb (author)  njrajgelani3 years ago
I learned all this in internet, some books and trying! Google now very thing! XD

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??
Nemweb (author)  guzz04 years ago
I don't know, but a several numbers of IR sensors have a solar light filter. The PHSC-38 have it.
is this universal??? Like can i take ANY IR code?
Nemweb (author)  Constantthinker432114 years ago
You can get almost all IR code
Nemweb (author) 5 years ago
I don't understand your question!
