In this simple circuit, we use a small BH1750FVI sensor on a breakout board and an Arduino to measure the illuminance in lux. Besides the application to measure the illumination of objects in the photography, you can – with an extension of this circuit – also easily make an adapted illumination of rooms or gardens. It is also possible to realize an automatic brightness control for displays.

Briefly introduced: BH1750FVI illuminance sensor on a small breakout board (GY-30)
With the BH1750FVI can be measured the illuminance in lux at a point. Areas of application are, for example, photography, automatic switching of lamps for lighting at night or dusk and much more.
