Measure light levels with this sensor module.
This module uses a Light Dependant Resistor (LDR) to produce an output voltage that varies with light level.
Connect it straight to your Arduino to build a night/day sensor, a sun tracker or combine it with a laser module to make a laser trip wire.


  • Arduino compatible
  • Operating voltage: 3.3 VDC or 5 VDC
  • Output: analog voltage
  • Pull-down resistor: 10 K. , on board
  • Dimensions: 25 x 15 mm
