infrapunalähet
Infrapunalähet, also known as infrared transmitters, are devices that emit infrared light. This light is part of the electromagnetic spectrum, falling just beyond the visible red light. Infrared radiation is often associated with heat, as warm objects naturally emit infrared energy. Infrapunalähet utilize this property to send signals wirelessly over short distances.
The operation of an infrapunalähet involves a light-emitting diode (LED) specifically designed to produce infrared wavelengths.
Common applications for infrapunalähet include remote controls for televisions, air conditioners, and other home entertainment systems.
