Smart Luxmeter is a tool in extended set of the Smart Tools collection.
This light meter measures the ambient brightness with embedded light sensor.
Usage is very simple. Make sure that your screen with the sensor is facing the ambient light source (lamp, LED lighting, window, sun...). If the sensor is facing your face or ceiling, the measurement will be poor.
In the morning or evening, sit by the window and measure the world getting bright or dark. It will be a funny experience.
The measured value can be used for reference, and optimized by [Calibration] menu.
