Product details

 

How it works:

The light sensor works by photoconductivity. When light falls on the sensor, its resistance changes. Higher light intensity produces lower resistance; lower light intensity produces higher resistance.

 

This light sensor can be used in projects such as:

  • Lighting control
  • Alarms
  • Motion detectors
  • Automatic irrigation systems
  • Light meters
  • Cameras

Example connection and testing with light-emitting diodes (LEDs):
