Enhanced Surveillance Systems: Mastering the Art of Monitoring Infrared LEDs

Monitoring infrared LEDs (IREDs) has become a crucial aspect of various industries, particularly in the realms of security, automation, and remote sensing. These devices emit infrared light that is invisible to the human eye but can be detected and measured to monitor environmental conditions, detect motion, or communicate wirelessly. This article delves into the world of monitoring infrared LEDs, exploring their applications, technology, challenges, and future developments.

Introduction to Infrared LEDs

Infrared LEDs are semiconductor devices that emit infrared light when an electric current passes through them. Unlike visible light, infrared light has longer wavelengths, typically ranging from 700 nanometers to 1 millimeter. This makes infrared light ideal for applications where visibility is not required, such as in security systems, remote controls, and communication protocols.
