What is an IR Blaster and How Does it Work?
An IR Blaster, also known as an infrared blaster, is a feature found in some smartphones that allows them to emit infrared signals. These signals can be used to control other devices, such as TVs, air conditioners, and DVD players, that have infrared receivers. The IR Blaster works by converting electrical signals into infrared light, which is then transmitted to the device being controlled. This technology has been around for decades and is commonly used in remote controls.
The IR Blaster in a smartphone is typically a small LED that emits infrared light when an electrical signal is applied to it. The light is modulated at a specific frequency to encode the command being sent to the device. For example, when you use your smartphone to control your TV, the IR Blaster emits a specific sequence of infrared pulses that correspond to the command you selected, such as changing the channel or adjusting the volume. The TV’s infrared receiver detects these pulses and decodes them to perform the desired action. This technology allows you to use your smartphone as a universal remote control, providing a convenient and centralized way to control multiple devices.
