wireless - Optical communication module using LED and photodiode or sensors

I'm trying to build a wireless communication system using LED and photodiode sensors. The communication distance is at most a few meters away, and the communication speed can be around 10kbps or even less. I try to use pre-built modules for sender and receiver systems as a turn-key system, but I found none so far.

• Do you know where can I find some modules/kits or whatever that does the LED communication?


• If there is none, is there any schematics or documents/books so that I can use to build one?
