https://www.rockwestsolutions.com/sensors/signal-detection-ir-beacons/ - Infrared (IR) light is light with a wavelength just slightly higher than what is visible by the naked eye but lower than microwaves. As such, IR light has a lot of practical uses for sending and receiving signals. The remote control that operates your television and DVD player are just two examples. IR light is emitted from almost all objects, with the signal amount determined by their physical properties as well as temperature. Moving beyond such simple household applications, Rock West Solutions works with organizations that need powerful IR beacons and software applications that use them.
