A radio module is an electronic device whose purpose is to transmit and receive signals through the radio channel, i.e., the range encompassing the range of frequencies from a single (ELF) even trillion Hertz (THF). Radio, as a form of wireless signal transmission is used in applications such as wireless alarm systems, remote control systems, automation systems, and devices equipped with smart sensors. In the digital radio modules of the encoding process of the transmitted signal through the so-called key frames of pulses, which involves the treatment of changes in the amplitude of the reference signal in digital form. Upon reaching the receiver, the signal is decoded in the form in which it was before encoding at the transmitter. Proceeded of information between radio modules, maybe as a voice message, text, a numeric value, the translation of the potentiometer or changing the switch position. So the link between radio modules was possible, require a power supply voltage and the auxiliary antenna.
Extensive application possibilities of radio modules
Especially popular among Amateur radio operators around the World, radio devices, operating at a frequency of 433 MHz, which works well for short distances up to several hundred meters and does not require a licence. Frequency 433 MHz is also popular in modeling the RC-based remote control for cars, riding, flying, floating, and other trinkets, allowing remote lock/unlock doors and activate/deactivate the alarm, for example, in buildings and cars. Because the command transmitter-receiver operating on the same frequency as with a single transmitter, you can transmit a signal to multiple receivers, and multiple transmitters can transmit to multiple receivers, creating, thus, a simple network of elements interacting with each other on the radio. If you are wondering how to make FM transmitter in digital technology, you want to connect relay RC elements of the installation of smart in Your apartment or to extend the capabilities of your project on the Arduino, the store Botland, you'll find radio module that will meet Your expectations.
