Digital Light Intensity Sensor Module (GY-49)
From Wiki
Introduction
MAX44009 ambient light sensor has I2C digital output, it can be widely applied in smart phone, laptop, industrial sensors and so on. With the working current less than 1µA, it is the ambient light sensor with the lowest power consumption in the industry and has 22-bit ultra-wide dynamic range (0.045lm~188,000lm). Because MAX44009 can detect extremely faint light, it can work well though covered by dark-colored glass.
