Description

The Grove Digital Light Sensor is a compact light sensing module based on the TSL2561 I2C light-to-digital converter. It converts light intensity into a digital signal and supports selectable infrared, full-spectrum, and human visible sensing modes, making it useful for projects that need more precise ambient light data than a simple analog photoresistor can provide.

The module works with Grove plug-and-play wiring and offers 16-bit digital output, 400 kHz I2C Fast Mode communication, a wide 0.1 to 40,000 lux dynamic range, and a programmable interrupt function with user-defined upper and lower thresholds.

Features

  • Selectable infrared, full-spectrum, and human visible detection modes
  • 16-bit digital output through an I2C interface
  • Supports 400 kHz I2C Fast Mode communication
  • 0.1 to 40,000 lux dynamic measurement range
  • Programmable interrupt function with upper and lower threshold settings
  • Grove connector for quick prototyping with compatible development boards

Applications

  • Ambient light sensing
  • Display or panel backlight control
  • Keyboard illumination control
  • Lighting-aware Arduino and microcontroller projects
