InfraRed Transmitter -> Receiver

[N468989]

Im working on a project and i would like know where i can find an ebook or site that could help me understand this technology. I will use an IR photodiode (Rx) and an IR emitter (Tx). the signal being sent will originate from a RS-232.

So basically i have RS-232 <-> IR <-> RS-232, and so i need to understand the properties of this communication medium.

To understand the basic current transfer ratios of IR links, you can browse the application notes at the manufacturers of the IR emitter and detector components (I would start with HP and Motorola).

To understand IR remote control subtleties, I'd start at wikipedia.org.

Unless you are going to use 1mm fiber (or similar) to confine the IR signal, you are going to deal with the same SNR issues that IR remote controls have to deal with. And dealing with those issues will push you away from baseband IR coupling of the RS-232 signals, IMO.

There are many resources available online that can help you understand the technology of IR transmitters and receivers. One good place to start would be to search for "IR transmitter receiver tutorial" or "IR transmitter receiver basics" on a search engine. This will bring up various websites, videos, and ebooks that cover the basics of IR communication.

You can also check out electronics forums and communities where people discuss projects and share their knowledge and experiences with different technologies. These forums can be a great place to ask questions and get advice from experienced individuals.

Additionally, many electronics manufacturers and suppliers have resources such as datasheets, application notes, and technical guides available on their websites that provide detailed information on IR transmitters and receivers.

Overall, with some research and a bit of experimentation, you should be able to gain a good understanding of the properties and capabilities of IR communication for your project. Good luck!
