China OEM IR Controller Supplier Factory

With the development of infrared technology, our life is more and more convenient. For example, as long as you return home and open the door, the porch light will naturally light up. Do you know why? Do you know how it works? This is all because IR controller. Let's discuss it together.

Development of infrared controller

Infrared (IR) technology dominates the remote device operation market. The IR controller sends encoded infrared waves to the IR receiver, where they are converted into device commands. The technology is best known for home remote controls, which have been able to operate almost any home entertainment device remotely since the mid-1980s. Beyond televisions, infrared controllers can operate almost anything that receives digital commands, from home appliances to cars and computer systems.

How does the infrared controller work?

The technology behind the infrared controller is deceptively simple. The panel on the device emits a brief infrared light when the button on the remote is pressed. This light is invisible to man; It's just out there in visible light. A receiver on the connected device reads the invisible flash and translates it into a command. In many ways, it works like Morse code, with the selection of long and short pulses corresponding to commands.

Because the technology works through invisible light, it has some of the same properties as visible light. The pulse train from the IR controller needs to be visible to the receiver. If a solid object blocks any of these parts, the signal will not pass and the command will not be executed. Properly placed mirrors, on the other hand, will allow light to bypass walls and enter other rooms.

When infrared controllers are able to penetrate walls or other solid objects, it may be more than just infrared. Since IR is just light, it can't do things that light can't do. When a remote control needs additional functionality, it usually includes a radio transmitter. In this case, the system will identify short radio pulses that do not reach the receiver and emit analog infrared signals. The signal will penetrate objects and travel farther than standard infrared.

To prevent infrared controllers from interfering with other devices, manufacturers install different codes into different systems. This basically means that all devices that support remoting use different languages. When a receiver sees a command it doesn't recognize, it simply ignores it. This opened the way for programmable remote controls; In essence, they can learn the language spoken by other devices, allowing one IR controller to perform multiple jobs.

What are the application of IR controller?

IR controller is only suitable for digital equipment. If a system has an on-board computer system, it can use the technology; Devices without digital systems cannot. Some manufacturers use digital receivers as intermediaries in analog equipment to enable IR communication. In these devices, the remote creates a digital response that activates analog functions -- it does not interact directly with the analog system.
