  • S: Signal output
  • +: VCC
  • -: GND

An infrared-receiver is a component which receives infrared signals and can independently receive infrared rays and output signals compatible with TTL level. It is similar with a normal plastic-packaged transistor in size and is suitable for all kinds of infrared remote control and infrared transmission.

Infrared, or IR, communication is a popular, low-cost, easy-to-use wireless communication technology. Infrared light has a slightly longer wavelength than visible light, so it is imperceptible to the human eye - ideal for wireless communication. A common modulation scheme for infrared communication is 38KHz modulation.

  • Adopted HX1838 IR Receiver Sensor, high sensitivity
  • Can be used for remote control
  • Power Supply: 5V
  • Interface: Digital
  • Modulate Frequency: 38Khz
  • Pin Definitions: (1) Output (2) Vcc (3) GND
  • Size: 23.5mm x 21.5mm
