Description of RF Transmitter-Receiver Pair
Quick Overview
The RF (Radio Frequency) Transmitter-Receiver Pair is an essential module for wireless communication over moderate distances. Using radio frequency signals, this pair enables seamless data transmission and reception across different devices, making it ideal for various applications such as remote controls, telemetry, and IoT (Internet of Things).
How It Works
The RF Transmitter takes data from a source (like a microcontroller) and encodes it into a RF signal, which is then sent through its antenna. The RF Receiver, on the receiving end, captures the RF signal via its antenna, decodes the data, and sends it to the destination device. Frequency modulation techniques are commonly used, ensuring reliable transmission.
