The main advantage of infrared technology in remote controls is its ability to communicate wirelessly over short distances using infrared light. This technology allows for energy-efficient transmission of signals without interference from obstacles, such as walls. Infrared remotes are widely used for devices like televisions and air conditioners. The primary benefit is their low cost and simplicity, as they do not require complex circuitry. However, the downside is that infrared communication requires a direct line of sight, limiting its range compared to other wireless communication methods.
