AnIR transmitter LEDemits IR light when powered. This light is not visible to human eyes, but can be captures by cameras. Hence commonly used in security camera, it can also be found in IR proximity sensor or line follower sensor in combination with IR receiver/photodiode. The specifications of the LED are

• Forward voltage: 1.2V
• Forward Current: 50mA
• Size: 3mm

Applications:

• Infrared applied systems
• Transmission system
• Object Detectionalong with Photodiode
• Optoelectronic switch
• Automatic Door Sensors
• Infrared remote control equipment
• IoT applications
