What Is an Infrared Transceiver?
An infrared transceiver is a device capable of both sending and receiving data through infrared light, which is invisible to the human eye.
This device operates by encoding data into electrical signals, which then drive an infrared LED to emit these signals as infrared light. On the receiving end, another module captures the infrared light, converts it back into electrical signals, and ultimately decodes it back into the original data. This seamless process enables the wireless transfer of information.
Common applications for infrared transceivers include remote controls for TVs and other electronics, wireless communication between devices, patient monitoring systems in healthcare, automation control in industrial settings, and enhanced security systems. Key advantages of this technology are its directional communication, which enhances security, its minimal power requirements, and its cost-effectiveness. Limitations include potential interference from physical obstructions and ambient light, which can disrupt signal transmission.
