  • InfraRED Receiver IC - distance to PIC?

    Hello,
    I am prototyping an IR remore control device. How far away can I mount the receiver IC from the PIC? Does it need to be up-close-and-personal?

    I plan on using the Vishay TSOP34838

    Thanks!

    Just talked with engineer at Vishay.

    The Resistor and Capacitor should be as close the the IR Receiver as possible. The IR Receiver can be up to 3m away! He also suggested placing a 4k7 or 2k2 pull-up resistor in the DATA line near the micro-processor for noise immunity and stability.

      Use a transistor to drive the infrared led

        While I suspect I'm taking this beyond the scope of your question, there is no limit to how far the IR receiver can be from the PIC. As mentioned above, a transistor driver will increase the range significantly, but it is also possible to use wired serial, radio, cellular, or IoT to connect to wherever you want the signal to go. Yes, I know... but I said I was going beyond the scope of your question, didn't I? Point is... it's not can I get it there, but how do I get it where I want it to go cheaply, efficiently, quickly, reliably...(insert priority here)?
