Intro: 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

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

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

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

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

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

    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

    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.

    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
