About this app

Smart Lux meter is a tool in extended set of the Smart Tools® collection.

This Light Meter measures the ambient brightness with embedded light sensor. It is used to adjust the lighting required for plants or to check the brightness of a study room.

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.

The measured value can be used for reference, and optimized by [Calibration] menu.

In the morning or evening, sit by the window and measure the world getting bright or dark. It will be an interesting experience.

This would be a better app if not for the ads which sometimes cause it to lag and freeze. Otherwise it works, the sound effects are kind of cool, could use a dark theme but ultimately I chose another light meter app with a cleaner interface, dark theme and no ads - much more efficient and isn't trying to connect to the internet all the time.

Doesn't work at all. Never asked permission to use the camera, but continually displays results around 180 - 220 Lux which is typical indoor light. Covering the camera, or putting it right in front of a calibrated 10,000 lux source it still displays figures in that range. This app appears to be nothing more than a random number generator.

I apologize for any inconvenience. The light sensor doesn't seem to work. Turn off the phone and turn it on again.

Very handy and easy to use app. Can be even better if possible to make areas and mean of the measurements. And export the data to an Excel or similar. Congratulations!
