Receiver: e.g. Vishay TSSP4038 IR sensor (tuned to 38 kHz) Ambient temperature range: 10 to 40° C. Here I’ve found a circuit with a Schmidt trigger that should do the trick, if there was a crystal oscillating at 38 kHz. But I can’t find any. Basic IR break beam setup? The 3 pin sensors from the link (VS1838B) might or might not work with continuous 38kHz IR. If they don't, modulated (interrupted) modulated (38kHz) must be used. That also requires more code on the receiver side. I currently use TSSP4038 (not TSOPxxxx) sensors for my beam break poject. They seem to be made for uninterrupted modulated IR. Leo.. 38kHz IR blaster | All About Circuits I'm trying to build a 38kHz IR blaster with 10 IR LED's. With the circuits I found here, I do not get enough range.
