It is perfect for adding wireless control to Arduino, ESP32, Raspberry Pi, or other microcontroller projects. This module provides reliable reception at distances up to 10 meters with its 38kHz carrier frequency.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e2.7V – 5.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCarrier Frequency\u003c\/td\u003e\n\u003ctd\u003e38kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtocol\u003c\/td\u003e\n\u003ctd\u003eNEC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReception Range\u003c\/td\u003e\n\u003ctd\u003eUp to 10m (line of sight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput\u003c\/td\u003e\n\u003ctd\u003eDigital active low\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePinout\u003c\/td\u003e\n\u003ctd\u003eGND, VCC, OUT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-arduino-clap-controlled-robot-car\"\u003eRemote-controlled robot car using Arduino\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eUniversal IR remote with learning ability\u003c\/li\u003e\n\u003cli\u003eWireless home automation for lights and fans\u003c\/li\u003e\n\u003cli\u003eIR signal repeater or extender\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eCompatible with any 3.3V or 5V microcontroller, including Arduino Uno, Nano, Mega, ESP8266, ESP32, and Raspberry Pi. Connect the OUT pin to a digital input and use the IRremote library for straightforward decoding. The wide voltage range makes it suitable for both 3.3V and 5V systems.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect VCC to 3.3V or 5V, GND to ground, and OUT to a digital pin (e.g., Arduino pin 2). No external pull-up resistor is required; the module includes built‑in filtering and demodulation circuitry. Keep the sensor’s face unobstructed for maximum range.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
