Topic: Long range IR emitter (Read 639 times) previous topic - next topic


Hi, everyone.

I'm actually working on an experimental project.

Basically what I'm trying to do some simple communication from an arduino via IR to multiple small devices.

The problem I have is that since the receiving side will be embedded into something really small, I need the emitter to have a range of approximately 80'  in all directions.

I've saw online that if I boosted the power of the IR light I could get a better range, but I dunno how far they are actually talking about.

I was hoping if there was some type of booster or extender I could just buy and plug in external power and give it a signal, however the ones I found were just extenders for the receiving side, not the emitter itself.

Is it possible to boost the emitter enough to reach this distance ? Or maybe I should just use bluetooth to transmit signals to controllers around the place, then emit IR signals from different locations to cover the entire place ? Or is there actually something i could purchase that works?

Any advice, comments are welcome.
