5mm IR Transmitter Receiver Pair

Description

Transmitter (IR LED):

• Size: The IR transmitter, or IR LED (Infrared Light-Emitting Diode), has a 5mm diameter, which is a standard size for through-hole components.
• Emission: The IR transmitter emits infrared light when powered. This light is typically not visible to the human eye but can be detected by IR-sensitive receivers.
• Wavelength: IR LEDs are designed to emit light in the infrared spectrum, typically around 940nm. The specific wavelength may vary depending on the model.
• Applications: The transmitter is used to send IR signals for various purposes, such as remote controls, data transmission, and object detection.
• Operating Voltage: The operating voltage for an IR transmitter usually ranges from 1.2V to 1.5V, and current typically ranges from a few milliamperes to a few tens of milliamperes.

Receiver (IR Photodiode or IR Detector):

• Size: The IR receiver, often referred to as an IR photodiode or IR detector, also has a 5mm diameter, matching the transmitter.
• Detection: IR receivers are sensitive to infrared light and can detect changes in the intensity of incoming IR signals.
• Wavelength Sensitivity: They are designed to be sensitive to the same or similar wavelength as the IR transmitter (around 940nm).
• Applications: The receiver is used to capture and interpret incoming IR signals. It’s commonly employed in IR remote control systems, proximity sensors, and more.
• Output: IR receivers typically provide a voltage or current output that varies depending on the intensity of the received IR light.
• Operating Voltage: The operating voltage of IR receivers may vary depending on the model and application but is typically in the range of 3V to 5V.
