At the same time you can observe the three columns of indicator LEDs on the module, each column for one photo-sensor.
When any of the sensors approaches the light source, the corresponding column of LEDs will brighten; the stronger light, the
more LEDs on. When the sensor gets away from the source, the LEDs will dim out. If the indicators are on when there's no light
source, you can adjust the potentiometers Rs1, Rs2 and Rs3 corresponding to the three sensors to dim the light. After the
calibration, the sensors then can achieve optimal effect.
