I have here an ir and a phototransistor but I dont know what is its code.. can you please give me a circuit how to use this?

 

Not without more information.

Can you describe the parts in details, perhaps by part numbers and/or photographs?

 

Hello,

As no information about the parts is given, I only can give some general information.
Have a look at the links of the following pages:

thanks sir this is what im looking for

 

i dont know the code of this transistor but i know the pinouts are..
see my attackment photo, the output of my photo transistor cant trigger the 6v relay.. can anyone here help me with this..

 

TSOP38238 ?

Those IR sensor modules require the incoming IR light to be flashing at 38000 Hz. That way, sunlight shining in the window or light bulbs don't trigger them.

Check if you can get the output pin to trigger with a remote control from your TV.

 

That is not a transistor. It is an integrated circuit with an IR photodiode, amplifier, level sensor, and open collector output driver. Probably.

sir using the tv remote i can trigger the phototransistor. but it wont work using the relay

how can i use it to trigger a 6v relay?

using the photo i've sent how can i determine the emitter base and collector of the phototransistor?

As Analogkid has already explained to you, the device you have is NOT, I repeat is NOT, a phototransistor. It is an IR decoder based on the Sony SIRC protocol. It is typically used in conjunction with a microprocessor as a remote control device. Perhaps if you gave us more information about your intended use we could be more specific about possible solutions. I have attached a datasheet which will give you the connection scheme and some application notes.

 

Kaiser, are you related to Rittesh by any chance...

No sir.

Thank you for your help sir. The circuit im looking for is done. I made a research about latch switch,Darlington connection, and the ir decoder. Combining these circuit came up into remote controlled switch.
