Infrared Receiver
IR Receiver

S: Signal output
+: VCC

An infrared receiver is a component designed to receive infrared signals and output TTL-compatible signals. It resembles a standard plastic-packaged transistor in size and is ideal for various infrared remote control and transmission applications.
Infrared (IR) communication is a widely used, cost-effective, and user-friendly wireless communication technology. Infrared light, with a slightly longer wavelength than visible light, is invisible to the human eye, making it perfect for wireless communication. A common modulation method used in IR communication is 38 kHz modulation.
