What is RF transmitter and receiver Arduino?

The RF transmitter receives serial data and transmits it wirelessly through through its RF antenna . The transmission occurs at the rate of 1 Kbps – 10 Kbps. RF receiver receives the transmitted data and it is operating at the same frequency as that of the transmitter.22 May 2020

An RF transmitter module is a small PCB sub-assembly capable of transmitting a radio wave and modulating that wave to carry data . Transmitter modules are usually implemented alongside a microcontroller which will provide data to the module which can be transmitted.

It is a communication library that allows two Arduino’s to communicate with each other using RF Module i.e. transmitter – receiver pair. This library consists of several functions that are used for configuring the modules, transmission of data by the transmitter module and data reception by the receiver module.
