How does Lumyeye Pro detect light?
Using the phone’s light sensor, Lumyeye Pro turns the surrounding light level into sound. A higher pitch indicates stronger light; as the light decreases, the pitch gets lower. You can listen to the change without needing to see the screen.
Before leaving a room, this helps you check whether the light is still on, so you can avoid unnecessary electricity use. If you want a brighter or softer ambience, adjust a lamp or dimmer and listen as the tone changes.
The detector is built into Lumyeye Pro on the phone you already carry. It offers an alternative to a separate light detector that may be heavy and expensive. The tone helps compare relative light levels; it is not a calibrated lux reading.
