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 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.
Features:
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
Applications
Ambient light sensing
Backlighting control for display panel
Keyboard illumination control
