  • Selectable detection modes: infrared mode, full-spectrum mode, and human visible mode
  • 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


This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal and can be used to measure the change in light intensity for various applications.

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, 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.
