Back to my Lumyeye Pro day

Hear how bright a room is

Lumyeye Pro uses your iPhone or Android phone’s light sensor to turn ambient light into sound. Brighter light produces a higher pitch; as the light fades, the tone becomes lower.

Using the light detector

Can the tone help me check whether a light is on?

Yes. Listen before leaving a room to check whether it is still lit. This can help avoid leaving lights on unnecessarily.

Can I adjust the lighting by ear?

Yes. As you brighten or dim a lamp, the pitch changes so you can choose a brighter or softer ambience. The tone shows relative light levels; it is not a calibrated lux reading.

Do I need a separate detector?

The feature is built into Lumyeye Pro on a compatible iPhone or Android phone with a light sensor. It offers an alternative to carrying a separate device.
