IR Infrared Emission Transmitter Module KY-005

AED 9.50



The KY-005 infrared transmitter module is capable of transmitting infrared signals at a frequency of 38kHz and a wavelength of 940nm, which falls outside the visible spectrum of human eyes. In Arduino projects, this module is typically used in conjunction with the KY-022 infrared receiver.



  • Operating Voltage: 5V
  • Forward Current: 30 ~ 60 mA
  • Power Consumption: 90mW
  • Operating Temperature: -25°C to 80°C (-13°F to 176°F)
  • Dimensions: 18.5mm x 15mm (0.728in x 0.591in)



  1. Signal (S): This pin is used to connect to the data or signal input of the module. It is typically connected to a digital pin on your Arduino or microcontroller to send control signals.
  2. GND (Ground): This pin is connected to the ground (0V) of your power supply or microcontroller.
  3. +V (Voltage): This pin is connected to the positive voltage supply (usually 5V) of your power source or microcontroller.

To use these modules, you'll need to include the Arduino-IRremote library. You can find the library at http://z3t0.github.io/Arduino-IRremote/, and it should be copied to your Arduino Library folder, typically located at "C:\User[UserName]\Documents\Arduino\libraries."
