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 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.
Selectable detection modes
high resolution 16-Bit digital output at 400 kHz I2C Fast-Mode
Wide dynamic range: 0.1 - 40,000 LUX
Wide operating temperature range: -40°C to 85°C
Programmable interrupt function with User-Defined Upper and lower threshold settings
Ambient light sensing

I am guessing I have to connect this to 3v. But I would like your advice.
Hi ,both of 5v and 3v3 can be use , because the input voltage it 2.7 - 5v
Can the i2c address of this module be changed so I may have multiple on the same buss?
Hi James.You might not change the address of I2C beacuse of the setting in circuit.
