Wireless RF Kit 433 Mhz (Transmitter+Receiver) module comprises an RF Transmitter and an RF Receiver.
The transmitter/receiver (Tx/Rx) pair operates at a frequency of 433 MHz.
An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin4.
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.
This low-cost RF transmitter can be used to transmit signals up to 50-100 meters (the antenna design, working environment, and supply voltage will seriously impact the effective distance).
It’s good for a short distance, battery power device development. 433 MHz is the operating frequency for transmitter and receiver pair.
