A telephone light sensor is a small handheld device used to detect if a telephone line is busy or on hold. It is held over a line to indicate line status which is signified through audible sounds or vibration.
The advantages of using a telephone light sensor include:
- it’s portability
- versatility, especially for people who work in an office environment
- simple to use (for example if lights are on or off)
- can be used to distinguish between green and red and other coloured LED lights by emitting different pitched tones (for audible models)
- emits loud and distinct tones (for audible models).
