I have Three Terminal Device Which Is used For receiving Infrared ray In Many remote Control Ckt, I want To know That It is Called as Some People Say it as TSOP,I.r. Receiver ,etc. Pls Clear My Doubt .......!

 

Can you provide more information about the device.

TSOP is a type of casing for an IC device.

 

It is Dark Black Color 1 pin (-ve) , 2 pin (+ve) & 3 pin (O/p)..........!

 

No idea.

Can you post a photo?

 

Actually in this case, TSOP is probably the starting part number for photo devices used by Vishay. The full number usually includes a code for the modulation frequency. Hence, TSOP32238 operates at 38KHz.

See: http://www.vishay.com/docs/81747/tsop322.pdf

Look at the top of the device with a magnifyig lense and see if you find the number. Then read its datasheet.

You Can see It in TV, STB & more I.r. appliance .!

 

Hello,

If you are looking for links about remote control, take a look at the links of this page:

On searching I get It, It Was Tsop & how to make More Than On/off Switch Of It Without Using a microcontroller.......!

 

Without ANY input from you, how are we supposed to know what the hell are you talking about?
Tsop means nothing more than a shape of the package. Unless you tell us what the device is or what´s written on it, there is no chance of helping you.

windoze_killa asked you a question. It is rude to ask for help without making any rational input, and ignoring questions from people who are trying to help you.

I assume some difficulty on the part of the OP with the King's English. But, that is not being rude. I am sure he does far better with English than I would do with his first language.

John, I know this is about some mystical three terminal device for infrared rays that probably has tsop written on it, but my point remains. Without his participation, this thread will go nowhere.

Rittesh: The requested photo, or ALL the actual letters on the device will be a great start to identify the device.

 

Ok, at the back of it written is SM0038 8HOCLJ...!

 

Means nothing, those are internal manufacturer's code #s

You've got an unidentified component you THINK might be an IR receiver. You came up with some valid # earlier indicating it may be from the TSOP family so the pinout is probably going to be the same, the internal function however would be unknown.

You could try writing to the manufacturer of the device but I wouldn't expect an answer as with most anything nowadays things like cable boxes are throw away equipment; they were never intended to be worked on from the beginning.

 

I believe that this is a link to the device in question. The manufacturer had the misfortune of using the four-letter abbreviation of a standard integrated circuit package in the part number.

Here is a link to a thread in which this device was discussed some time ago.

Yes, sir is right as i was using it as on/off switch from remote control & now i want to make more than on/off switch without using microcontrollerin this circuit pls help...!

 

Can you attach a schematic of what you have tried so far?

hgmjr

 

Simple, I have taken o/p from Tsop & connected with transistor.......?

 

Remote control without a microcontroller will require something like a pair of these chips ...

You will have to test the detector but the most common types run at around 38Khz and produce a fixed lenght output pulse when a burst is detected at the carrier freequency ....

Here is 1 datasheet (TSOP1737) ... and links to simmilar units.

Remember I am only saying that this is a posibility, you will still have to test.

A lot of those detectors require ten pulses then a waiting period of at least two pulses.

In other words they are controlled by a microprocessor both at the emitter and the detector stages. You can however fool them by using a pair of 555 ICs to set the frequency and provide the delay.
