Infrared Blaster – The Device that Blasts Your Commands
Have you ever wondered how your remote works? How can you control your TV or Speakers from a small device that has no Bluetooth? Your TV or cable box receives your commands from your remote and has an IR Blaster. It is a small device in all remote controls and allows us to control our TV from a distance. In this article, we will see what an Infrared Blaster is, where it is used, and more.
What is an Infrared Blaster?
Your devices have all kinds of cool technology that are so small that you might not even be aware of them. They are always performing functions that make your life easier no matter the quality of your device. One such technology or device is the infrared Blaster in your remote control and cable box. This small device lets you give commands to your remote that it carries out on your cable. It works so fast that you don’t even think twice about it.
How does Infrared Blaster work?
Infrared Blaster does exactly what its name says. It blasts infrared light from the device it is installed in to communicate with the other device that has an Infrared sensor. This sensor receives the infrared lights blasted by this blaster and performs the command given to it. The most common place to find an Infrared Blaster is in your remote and its sensor in the TV.
In the past Android mobile phones also had Infrared Blasters that allowed them to control the TV or Speaker without using a Bluetooth or wifi connection.
What is Infrared?
Infrared is a light that has to be able to reach its sensor for it to perform the assigned task. This is also why your remote works better when in a straight line with the TV. It is also the reason your remote control stops working after a certain distance and from certain areas of your house. You might have seen a red light going off when you press your remote on your TV as well as the top of your remote. This red light is the infrared light that has been blasted through the Infrared Blaster.
