What is the RF Module (Transmitter & Receiver)
https://www.nicerf.com/articles/detail/what-is-the-rf-module-transmitter-receiver.html
What is the RF Module (Transmitter & Receiver) The RF module, as the name suggests, operates at Radio Frequency. The corresponding frequency range varies between 30 kHz & 300 GHz. In this RF system, the digital data is represented as variations in the amplitude of carrier wave. This kind of modulation is known as Amplitude Shift Keying (ASK).

433 MHz RF transmitter and receiver. Use to send audio or data signals, or use as a remote control on/off switch. With a few extra parts you can use these modules in a variety of applications. Right-angle headers (0.1" spacing) plug into solderless or solderable breadboards, for convenient experimentation.

Basically the RF modules are 433 MHz RF transmitter and receiver modules. The transmitter draws no power when transmitting logic zero while fully suppressing the carrier frequency thus consume significantly low power in battery operation. When logic one is sent carrier is fully on to about 4.5mA with a 3volts power supply.
