Because the module contains a 38-KHz pulse generator, you can save a few code lines and, of course, one or two I/Os of your microcontroller when making advanced infrared projects. See the schematic ...

We’d also like to mention the resistor and capacitor suggested for filtering the IR receiver module signal. We’ve included the recommended application schematic for that part after the break.

The IR receiver module is represented here by IRRX, powered from a 5-Vdc supply. An infrared emitter (IRED) is available for changing the hardware as an IR encoder. LED1 indicates the IR signal ...

The XIAO Smart IR Mate is a compact circular-shaped IR remote hub/blaster built around the XIAO ESP32-C3 and designed for IoT ...

The circuit is viewed from the component side of the PCB. It's quite a simple circuit. The IR receiver module and other parts were purchased from Jaycar Electronics here in New Zealand - it is a 38kHz ...

Melding together a photodetector and preamplifier in a single package, the TSOP7000 IR receiver features a 455-kHz carrier frequency and is optimized for use in multimedia end-products. The module ...
