1. Introduction
This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a
digital signal. Different from traditional analog light sensor, as
Grove - 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 among 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.
