The Light sensor module uses the GL5528 photoresistor to detect the light intensity of the environment. The resistance of the sensor decreases when the light intensity of the environment increases. The chip LM358 is used as a voltage follower to enable you get a accurate data.



  • Grove compatible interface
  • Wide supply voltage range: 3V-30V
  • Miniature HID part
  • Easy to use light sensor module
  • Resistance decreases as luminance increases
    • Low resistance (in bright light) triggers a HIGH signal towards the output module
    • High resistance (in darkness) triggers a LOW signal towards the output module
  • Easily integrates with Logic modules on the input side of Grove circuits
  • Uses Standard 4-pin Grove Cables to connect to other Grove modules such as Grove Power Modules, Logic Gates and Grove - Base Shield


Applications Ideas:

  • Electronic toys
  • Light-control switch
  • Monitor



  • Voltage: 3-5V
  • Supply Current: 0.5-3mA
  • Light resistance: 20KΩ
  • Dark resistance: 1MΩ
  • Response time: 20-30 secs
  • Peak Wavelength: 540 nm
