Infrared LED 5mm/ 940nm: Blue

Key features

• Wavelength: 940 nm, making the light invisible to the human eye, avoiding the visible red glow associated with 850 nm IR LEDs.
• Diameter: 5 mm, a standard size for many electronic circuits and applications.
• Illumination Beam: Typically a 20-degree beam angle, although this may vary according to the specific model.
• Operating current: Can operate in continuous mode with a current of 100 mA, or in pulse mode with a current of up to 1 A.
• Forward Voltage: Typically 1.6 V.

Applications

• Video surveillance and night vision: Used in security cameras to improve night-time visibility without producing a visible glow, particularly useful for applications where discretion is required.
• Remote Controls and Remotes: Used in TV remotes and other devices for wireless communication, because of their invisibility and power.
• Motion Sensors and Security Systems: Integrated into motion sensors and security systems to detect movement without being visible.
• Biometrics and Recognition Applications: Used in biometrics applications, such as facial recognition, and in Automatic Number Plate Recognition (ANPR) systems.

Project examples

• Video Surveillance Systems: Integrated into security cameras to provide invisible infrared illumination, allowing clear night vision without alerting those being monitored.
• Remote Controls and Remote Commands: Used in the construction of remote controls for televisions, household appliances, and other devices requiring discreet wireless communication.
• Robotics and Automation Projects: Used in motion sensors and detection systems for robots and automated systems, where invisible detection is crucial.
• Photography applications: Can be used to create intervalometers for cameras, enabling automatic shots to be taken at regular intervals.
