What is IR Controller?
Infrared technology (IR) is most of the market for remote equipment. The IR controller sends coded infrared waves to the IR receiver where they are translated into the device commands. This technology is best known in the remote control of the household, a device that is remotely operated by almost every home entertainment device from the middle of the 80's. In addition to TVs, the driver can operate almost anything that receives digital commands, from household appliances to cars and computer systems.
IR technology is deceitly simple. When the button is pressed on the remote control, the panel on the device releases a short explosion of infrared light. This light is invisible to people; It's just out of visible light. The receiver reads invisible flashes on the connected device and converts them to the command. In many ways, it works like a Morse Code, a selection of long short pulses that correspond to the command.
Odtechnological functions through invisible light has some withTejná properties like visible light. Burst emitted by the IR driver must be in the place where the receiver can see it. If fixed objects block one of the parts, the signal cannot pass and the command will not be started. On the other hand, properly placed mirrors allow the light to bend around the walls and other rooms.
When the IR driver is able to penetrate walls or other solid objects, it is probably not just IR. Because IR is just light, she can't do anything that light can't do. If the remote control needs additional functions, it will usually include a radio transmitter. In this case, the system recognizes that the signal does not reach the receiver and emits a short rip rip that mimics the IR signal. This signal penetrates objects and travels much further than standard IR.
In order to keep the manufacturer to interfere with other devices, they install different codes in different systems. This basically meansthat all devices with a long -distance manner speak different languages. When the receiver sees a command that does not recognize, it simply ignores it. This opens the way to programmable remote controls; In essence, they can learn the language spoken by other devices, allowing one IR controllers to work several.
IR controller only works on digital devices. If the system has a on -board computer system, it can use this technology; Devices without digital systems cannot. Some manufacturers put digital receivers into analog devices as an intermediary to allow IR communication. On these devices, the remote control creates a digital response that activates the analog function - directly does not interact with the analog system.
