Working Principle of 433MHz Module

The RF 433MHz transmitter converts digital data from a microcontroller into a radio frequency signal using Amplitude Shift Keying (ASK) or On-Off Keying (OOK) modulation. This RF signal is transmitted through an antenna into the air.

The receiver module captures the RF signal through its antenna and demodulates it back into digital data. This data is then read by the receiving microcontroller.

To ensure reliable communication, encoding and decoding techniques are typically used through software libraries, which help reduce noise and improve data integrity.
