Infrared technology is as old as the world. In fact, it is literally so because infrared waves reach us from the sun. When it comes to technology, infrared waves can be found, for example, in TV remote controls, not the current ones, but those produced many decades ago. Currently, infrared technology is much more modern.

How does infrared communication work?
Infrared radiation, to put it simply, is light that is invisible directly to the human eye and therefore works well in wireless communication. Sources of infrared radiation are present among us in many places. Sunlight, electric lighting and any objects that emit heat also make up the infrared radiation spectrum. How was the problem of interference-free communication between devices equipped with an infrared module solved among such a large number of infrared sources? When you press a button on the TV remote control to, for example, change the volume or the broadcast program, the infrared LED built into the remote control (IR sensor) flashes at a frequency of 38kHz (this is the most common frequency in IR devices, but other frequencies are also found, e.g. 36kHz or 56kHz) to send encoded information to the IR receiver built into the TV. In order for the signal transmitted to the infrared receiver to be received correctly, it must be modulated. Using this process, the sent signal is given an appropriate time course shape, thanks to which it is correctly recognized and decoded in order to change the parameter depending on the button pressed on the remote control.
Wide possibilities of cooperation with a mobile phone and Arduino
The standard in most modern touch phones is a built-in infrared sensor that detects the temperature of the human body and controls the display on and off during voice calls. Using the infrared connector to your phone, you can pair your phone with the infrared module, giving you many options for controlling external objects. Then, from your phone, you can manage the operating parameters of air conditioning devices, control the blinds of doors and windows, and even use your phone as a game console. Connecting the IR sensor to Arduino will allow you to build, among others: a robot with the function of detecting obstacles in its movement path, as well as an intelligent lighting control system in the room. Choose the right infrared sensor for your project.
Infrared receivers - FAQ
An IR receiver (infrared receiver) is an electronic element that enables the reception of a signal transmitted using electromagnetic radiation waves in the infrared band.
The infrared receiver is used to receive signals from IR transmitters. They are used, for example, in remote controls for electronics and household appliances, robots and electronic equipment.
It is best to do this by connecting the receiver according to the diagram and sending a signal from the diode to it, and then reading the changes in the output signal with a meter .
The simplest way is to look at the IR diode through the smartphone's camera, which records infrared radiation - the working diode will glow in its lens.
