This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal. Different from the traditional analog light sensor, as Puzzle Light Sensor, this digital module features a selectable light spectrum range due to its dual light sensitive diodes: infrared and full spectrum. 

You can switch between three detection modes to take your readings. They are infrared mode, full-spectrum and human visible mode. When running under the human visible mode, this sensor will give you readings just close to your eye feelings.
