433 MHz Wireless Receiving and Transmitting Module is a commonly used set of radio frequency (RF) modules that allow wireless communication between two devices. These modules typically operate in the 433 MHz frequency band, which is a popular frequency used for low-power, short-range communication. Here's a breakdown of the key components
433 MHz Transmitter (TX): This is the module that sends out a radio signal at 433 MHz. It takes input data and transmits it wirelessly over short distances. It is typically connected to a microcontroller (like an Arduino or Raspberry Pi) to send data.
433 MHz Receiver (RX): This module receives signals transmitted at 433 MHz. It takes the received data and sends it to the connected microcontroller for further processing or action.
