ACEBOTT IR Remote Controller Module for ESP32/Arduino

Connect the module's VCC pin to ESP32's 3.3V output, GND to ground, and the signal output pin to a GPIO pin of your choice (e.g., GPIO 4). Ensure you use a current-limiting resistor (100-220Ω) in series with the IR LED transmitter pin if you are sending signals. For receiving, the digital output pin can be connected directly. Install the IRremoteESP8266 library in Arduino IDE to begin decoding and sending codes.

The module receives raw 38kHz modulated IR signals compatible with common protocols like NEC, Sony SIRC, RC5, and Samsung. To decode them, use an Arduino library such as IRremote or IRremoteESP8266. Initialize the IR receiver object with your chosen GPIO pin in your setup() code. The library will capture incoming signals and provide the decoded protocol type, command value, and address, which you can then use to trigger actions in your project.

Yes, this is a transceiver module capable of both transmitting and receiving 38kHz infrared signals. The receiving distance is up to 15 meters under ideal conditions with a clear line of sight, and the receiving angle is approximately ±35 degrees. For transmitting, the effective range depends on the current supplied to the IR LED; typical ranges are 5-10 meters. Always point the IR LED directly at the target device's receiver for best results.
