RF communication is used in many industries including television broadcasting, radar systems, computer and mobile platform networks, remote control, remote metering/monitoring, and many more. Humankind communicates with artificially created radio waves that oscillate at various chosen frequencies. RF waves occur naturally from sun flares, lightning, and from stars in space that radiate RF waves as they age. RF propagation occurs at the speed of light and does not need a medium like air in order to travel. Frequency refers to the rate of oscillation. Radio waves are a form of electromagnetic radiation with radio frequencies that range from 3Hz to 300 GHz.
It has many application in embedded system projects. So lets get start with introduction to these modules. A radio frequency (RF) signal refers to a wireless electromagnetic signal used as a form of communication. RF Transmitter and Receiver Module Interfacing with Arduino: In this article you will learn how to interface RF transmitter and receiver module with Arduino and how to send data from RF transmitter to RF receiver.
