RF Modules

RF modules (Radio Frequency module) are electronic devices used to transmit and/or receive radio signals between two devices. RF modules operate at Radio Frequency of 20 kHz to 300 GHz. An RF module comprises of an RF Transmitter and an RF Receiver. The transmitter/receiver (Tx/Rx) pair operates at a frequency of 434 MHz. An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna, and the transmission occurs at the rate of 1Kbps - 10Kbps. The transmitted data is received by an RF receiver operating at the same frequency as that of the transmitter.
