🚨 Important Notes Before Buying & Usage Guide

❌【Product Clarification & Limitations】

This is NOT a Universal Remote! This is an electronic component kit. It requires you to use it with a development board (like Arduino), write code, and learn about IR protocols to achieve remote control functionality. It cannot directly replace or control your appliances unless you complete the decoding and programming work.

One-Way Communication Only:

This is a transmit/receive kit for one-directional communication. It does NOT support bidirectional data exchange like Bluetooth/Wi-Fi.

⚠️【Common Misconceptions & Misuse】

Do NOT use for safety-critical systems! Not recommended for access control, security, or any high-reliability applications, as the IR signal can be easily interrupted by strong light (e.g., sunlight).

Range & Angle Limitations:

The advertised 10m range is the maximum under ideal conditions. Actual effective distance and angle can be significantly reduced by ambient light, obstacles, transmitter power, and receiver sensitivity.

Coding Protocol Variance:

Different brands (e.g., Sony, NEC, Samsung) use different IR coding protocols. This module only transmits/receives the 38KHz carrier signal. Decoding a specific protocol requires your own research and programming.

✅【Prerequisites & Skill Level Required】

Required Knowledge: You need basic experience with Arduino (or similar platforms), including circuit connection, using libraries, and writing simple code.

Required Equipment: You must provide your own Arduino board (e.g., Uno, Nano, ESP8266), USB cable, jumper wires, and a 5V power source (e.g., USB charger or 18650 battery pack).

Learning Preparedness: It's recommended to have some preliminary understanding of "Infrared Remote Principles" and the usage of the "Arduino IRremote Library".

🔧【Safety Warnings & Operational Notes】

Voltage Match:

Strictly use 5V DC power supply. Exceeding 5.5V may cause permanent damage.

Correct Wiring:

Double-check the pin definitions (VCC, GND, DATA) before connecting to your board. Reverse connection or short circuits may burn out the chip.

ESD Protection:

It is advisable to wear an anti-static wrist strap when handling the modules, especially in dry environments.
