More info

Detail about of Light Sensor, detects the ambient light intensity, I2C interface


  • Features TSL2581FN with ADC, feels the ambient light just like human vision
  • I2C interface directly outputs the ambient light intensity value, needs no calibration, less noise interference
  • Embedded infrared photodiode, gets high precision output even in environments with strong infrared noise interference
  • Features interrupt output, programmable upper/lower thresholds
  • Sensitivity is about 30 times higher than TSL2560/TSL2561
  • Embedded voltage level translate circuit, allows directly connecting to 3.3V/5V MCU systems


  • Resolution: 16 bit
  • Operating voltage: 3.3V ~ 5V
  • Dimension: 25mm × 15.5mm
  • Mounting holes size: 2.0mm

How to Use

In the case of working with a MCU:

  • VCC ↔ 3.3V ~ 5V
  • GND ↔ GND
  • SDA ↔ MCU.I2C data pin
  • SCL ↔ MCU.I2C clock pin
  • INT ↔ interrupt output, optional
