RF Transmitter and Receiver Circuit with Arduino Video
What is RF Transmitter and Receiver Circuit
The most commonly used electrical module these days is RF Transmitter and receiver circuit. Both the devices work together to transmit the signal from one end to other. There are many devices involved in this circuit to complete the process of transmission.
The term ‘RF’ in RF transmitter stands for Radio Frequency. Radio frequency is generated through a small electronic device with the help of which you can easily transmit signals between any two devices which work on radio frequency waves. Usually, all the RF modules work with the help of a transmitter and receiver that is why it is known as a RF transmitter and receiver circuit.
A small RF transmitter can easily transmit a radio wave and even can do modulation that wave to carry the data along. In a circuit, RF transmitter should be placed or joined next to the micro controller. This micro controller provides data to the module which can be transmitted with the help of this RF module. Different RF transmitters are operated at different frequencies, according to the wavelength of the frequency the RF transmitter and receiver circuit is set up.
The main function of the receiver circuit is to receive the modulated signals transmitted via RF transmitter. When this module receives the signals then it further demodulates it for RF communication to occur between two ends. There are various types of RF Receiver circuit; you can use the one which fits in your budget and process the most for better and productive results.
How to use RF Transmitter and Receiver Circuit
A RF transmitter and receiver circuit diagram is only complete when it has a proper RF transmitter, RF receiver, battery, antenna and pins to connect all these devices. This basically works as a wireless on or off switch. And, the main purpose of this complete circuit is to send pulses from its antenna to a RF receiver.
It is recommended to always use a continuous wave RF transmitter, so that you do not need to modulate the radio frequency waves. Nowadays, this circuit has wide number of applications as it has made the wireless transmission a lot easier than before.
The most common example of a device which works on RF transmitter and receiver circuit is our remote controls. Almost, each one of uses remote everyday but do we ever wonder how it works from such a long distance. The simple mechanism with the help of which you can easily access your television through a remote is through a RF transmitter and receiver circuit. And, not only all the television remotes, even all the other remotes which you use have this circuit within them for its functioning.

All the major wireless transmissions occur through this RF transmitter and receiver circuit only, like wireless meter reading, wireless data terminals, wireless data transmissions, wireless home security systems and lot more.
To make sure that the performance of your circuit is not hindered, you need to see that the circuit is properly attached or not. And, some other factors which can affect the performance of the circuit are worn out batteries or insufficient transmitter power.
These are all the points you should keep in mind while setting up or using a RF transmitter and receiver circuit.
