⚠️ Important Notes:

• These modules transmit raw digital data and require encoding/decoding (e.g., using VirtualWire, RCSwitch libraries, or HT12E/HT12D encoder/decoder ICs) for reliable communication.

• Range varies with supply voltage, antenna, and environmental conditions.

• For optimal performance, use a proper 17.3cm antenna (1/4 wavelength) on both modules.
