Motion Sensor Light solutions are devices that detect the amount of visible light from a surrounding or a light source. In this context, the measurement of light sensor output is lux. It is the term used to measure illuminance, in other words, the area where the luminous flux is spread.
Light sensors have their use cases in monitoring the brightness of an area in an office. For example, this has a use case for both the building tenant and the building owner. The tenant can seek the most suitable working environment for their working needs, and the building owner can gather data on how the lighting affects the space usage.
