Grove Digital Light Sensor (TSL2561)

The TSL2561 is controlled and monitored by sixteen registers (three are reserved) and a command register accessed through the serial interface. These registers provide for a variety of control functions and can be read to determine the results of the ADC conversions. Different from the traditional analog light sensor, such 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. With its high-resolution and wide operating temperature range, you can use it to measure the change in light intensity in various light situations with many popular microcontrollers. Highlighted Features Flexible detection modes: Infrared mode, full-spectrum mode, and human visible mode selectable High-resolution: 16-Bit digital output at 400 kHz I2C Fast-Mode Support measurement in various lighting situations: Support a wide dynamic range of 0.1 - 40,000 LUX and a wide operating temperature range of -40℃ to 85℃ Programmable interrupt function: User-Defined Upper and lower threshold settings Grove unified socket: The product ensures "Plug and Play" and could be versatile for various applications of Grove Applications Ambient light sensing Backlighting control for the display panel Keyboard illumination control Documentation Data Sheet
