This is how Remote Control works

science and technology

The remote controller, one of the most important devices we rely on in many of our daily life, from TV to adapt to lighting and other things, but did you ever think of the mechanism through which the remote control works, .

Remote Control:

The remote controls the transmission of instructions non-wirelessly through infrared or radio waves and sometimes ultrasound.

Infrared:

The IR is produced by a small electronic component called an infrared diode, which converts an electrical signal with a voltage of about 1.5 volts to a signal from infrared light. The wavelength of the radiation ranges from 800-1000 nanometers. The transmission to the remote control is approximately 940 nm, and the system has become very common and the system is used to give orders to different types of devices.

How the remote works:

In the IR, the digital message sent by Remote Control consists of a binary code. The binary system is used to represent the numbers 0 and 1, and the message format is divided into parts, where the first part is the starting code for transmission, The message has the information associated with it, as well as the identification code of the receiver device, which is important to distinguish the special controller.
