Grove - Digital Light Sensor - TSL2561

This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity into a digital signal. It has three detection modes to take your readings (infrared mode, full-spectrum, and human visible mode) and can be used to measure the change in light intensity in various light situations with many popular microcontrollers.

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 with User-Defined Upper and lower threshold settings

Description

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.
