Key Features: Emitter LED: Emits infrared light.

Used to send signals for remote controls or sensors.

It usually has a transparent or slightly colored capsule.

Receiver LED (Photodiode): Detects incoming infrared light.

Used to capture the signal from the transmitter led.

Usually has a dark black capsule.

Size: Diameter of both components is 5mm.

Voltage: Typical operating voltage is between 1.2V-1.5V.

Wavelength: The most common wavelength is 940nm, a range that the human eye cannot see.

Uses: It is used in many electronic projects such as remote control systems, obstacle detection sensors, line tracking robots and various security systems.
