Infrared IR Receiver Module for Arduino

Consumer IR remotes (TV remotes, universal remotes, most hobby IR remotes) all modulate their signal around the 38kHz band specifically because it's the frequency ordinary ambient light and electrical noise doesn't produce - this receiver is built around the widely-used 1838 receiver IC tuned to 37.9kHz for exactly that reason, filtering out interference that would otherwise show up as false button presses. The demodulated signal comes out as a straightforward digital pulse train on the DO pin, ready for a library like IRremote to decode into actual button codes.

An 18-meter rated receiving range and 90-degree reception angle give it plenty of margin for typical indoor remote-control distances, and the double-shielded package specifically guards against electrical interference from nearby motors or switching supplies that could otherwise corrupt the received signal. A simple three-pin interface (VCC, GND, DO) means it wires directly into any microcontroller with no additional support components.

Common uses are adding remote-control input to a DIY project using any standard IR remote already lying around, replicating consumer remote functions in a home automation build, and robot or appliance projects wanting simple wireless control without a full RF or Bluetooth module.
