433MHz RF Transmitter Receiver Wireless

433 MHz RF Transmitter and Receiver module pinout, features & working
The 433 MHz RF transmitter and receiver module is a pair of small RF (i.e. radio-frequency) electronic modules used to send and receive radio signals between any two devices. The transmitter module sends the data from the transmitter end and the Receiver module receives that data at the receiver’s end.
VCC Used to power the RF receiver module.
GND Ground pin of the module. Connect it with the controllers and encoder/decoders GND pin.
DATA This is the data pin of the transmitter. It takes the data from the microcontroller or encoder and broadcast it via the antenna.
ANT The antenna pin is not necessary to use but it is recommended. The module can only operate max 3 meters without an antenna but its range can be extendable up to 100 meters by using a small hookup wire as an Antenna

433MHz RF Transmitter Module Features:
The Transmitter offers only one-way communication through 433.92MHz frequency at 1Kb data rate
It operates at a range of 3-12V which is also the power operating volts of most of the microcontrollers and boards.
The module uses the ASK (Amplitude Shift Key) modulation method to transmits the data.
It is one of the very low-cost power effective modules for both commercial, hobbyist, and developers.
433MHz Transmitter is one of the cheapest RF transmitters and it has a lot of applications and can be used interface with almost every microcontroller.
433MHz RF Receiver Module Features:
The RF receiver delivers the output to the data pin in an encoded form.
The operational voltage range of the module is 5V maximum.
The frequency of the receiver can be changed using a node present on it.
It is one of the popular and cheapest receivers and has low power consumption.
433MHz RF receiver module uses the ASK signal as an input.
