Infrared sensor extenders are devices that amplify and relay infrared signals, allowing for increased range and improved functionality of remote-controlled devices. These extenders typically consist of an IR receiver, a signal processor, and one or more IR emitters. They can significantly enhance the operational range of IR-based systems, overcoming obstacles and environmental interference. This article explores the capabilities, installation process, and troubleshooting techniques for infrared sensor extenders.

- Commercial IR repeater systems often reach 10-20 meters
Minimum Range:
- Standard IR remotes and receivers typically have a minimum range of 1-2 meters
Factors Affecting Range:
- Environmental conditions (sunlight, room lighting)
- Obstacles (walls, furniture)
- Temperature of transmitter and receiver
- Power of IR LEDs
- Sensitivity of receivers
