Understanding how to read the light graph in the Airthings app for Wave Enhance and answering what is lux?

Light sensor specifications

Photodiode

The sensor reports light intensity in lux units which uses a scale from 0 to 100,000.

The lux readings will vary depending on the position of the monitor with respect to the room’s light sources. To compare light intensity over time, we recommend that you avoid moving the monitor or changing its position. For more information, check out this support article.

What is lux?

Lux is a unit of measurement for light intensity, specifically for the amount of light that illuminates a surface. It is defined as one lumen per square meter. In simpler terms, lux measures how much visible light is cast on a given area.

The higher the lux value, the brighter the light on that surface. Lux is commonly used in contexts such as photography, architecture, and workplace lighting standards to ensure adequate lighting levels for various tasks and environments. For example, a brightly lit office might have around 500 lux, while a sunny day outdoors could have over 100,000 lux.

Does the placement of my Wave Enhance affect the measurement readings?

Yes, orientation affects measurements. For the ambient noise and light sensors, the direction the device faces matters (towards or away from the source). It should not be placed near windows or vents as it could affect the readings. To learn more about monitor placement view the article here.
