What are radio modules and how do they work?

A radio module is an electronic device whose task is to send and receive signals via radio, i.e. in a frequency range from single (ELF) to even trillions of hertz (THF). Radio transmission, as one of the forms of wireless signal transmission, is used in applications such as wireless alarms, remote control systems, automation systems, as well as devices equipped with intelligent sensors. In digital radio modules, the process of encoding the transmitted signal takes place through the so-called pulse keying, which involves converting changes in the amplitude of the carrier signal into a digital form. Once it reaches the receiver, the signal is decoded into the form it was in before being encoded at the transmitter. The information transmitted between radio modules can be a voice message, text, numerical value, adjustment of a potentiometer or change of switch position. To enable communication between radio modules, an auxiliary power supply and antennas are needed.

Extensive possibilities of using radio modules

Particularly popular among radio amateurs around the world is radio transmission using devices operating at the 433MHz frequency, which works well over short distances of up to several hundred meters and does not require an appropriate license. The 433MHz frequency is also popular in RC modeling, in remote control equipment for driving, flying, floating and other vehicles, as well as in remote controls enabling remote locking/unlocking of doors and activation/deactivation of alarms, e.g. in buildings and cars. Since the transmitter-receiver unit operates on the same frequency, one transmitter can send a signal to many receivers, and many transmitters can send a signal to many receivers, thus creating a simple network of elements communicating with each other via radio. . If you are wondering how to make an FM transmitter using digital technology, want to connect a radio-controlled relay to elements of an intelligent installation in your apartment or expand the capabilities of your Arduino project, in the Botland store offer, you will certainly find a radio module that will meet your expectations.
