Ambient Light Sensors Slide 14

Shown here are two electrical response graphs for the BH1700 family. The left graph indicates that the digital light sensor supply current demand is not greatly influenced by the luminosity. The right graph represents luminosity vs. output serial data measurement results for H, M, and L gain modes. High-gain mode has the most accuracy and can measure in 1 lux increments. Medium-gain mode can measure in 4 lux increments, while Low-gain mode can measure in 32 lux increments.
