1.9 BRIGHTNESS SENSOR
Display board LED brightness can be set manually (from the menu or software) or assessed
automatically depending on the ambient light detected by the brightness sensor in the upper left
corner (4th row, 5th column). There are other sensors for each 32x32 LED area, but only the one in
the upper left corner is used for active control.
The minimum-maximum brightness values range from 1 to 100%, although in the default settings
60 is the maximum value. This means that the maximum brightness value that can be set
automatically by the sensor is 60. Normally this value is enough even in case of strong light or
sunny days. If you want to increase brightness (which causes higher power and battery
consumption), set 1 – 100 as minimum and maximum value so that the sensor can set higher
values. Of course it is possible to set Brightness Type = Manual (instead of Automatic) and to
choose a fixed brightness level (see par. 2.1)
