Introduction to LED IR 940nm

LED IR 940nm refers to an infrared LED with a peak emission wavelength of 940 nanometers. It is widely used in remote controls, security systems, and other applications due to its ability to transmit signals over short distances without the need for line-of-sight communication. Unlike visible light, infrared radiation is not visible to the naked eye, making it ideal for concealed communication and detection purposes.

Working Principles of LED IR 940nm

LED IR 940nm operates on the principle of emitting infrared light with a specific wavelength. When an electric current passes through the LED, it generates infrared radiation at 940nm. This radiation is then transmitted through the air or other media to the receiver, which converts it back into an electrical signal for further processing.

The working process of LED IR 940nm can be summarized as follows:
1. Electric current passes through the LED, generating infrared radiation at 940nm.
2. The infrared radiation is transmitted through the air or other media to the receiver.
3. The receiver converts the infrared radiation into an electrical signal.
4. The electrical signal is processed and decoded to obtain the desired information.
