Photoresistors, Light Dependent Resistors or LDRs are basically light sensors. They adjust their resistance based on the light they are exposed to. They are made with semiconductor materials which alter their properties with the change in light intensity.

In short, an LDR will show a very high resistance when in dark environments and low resistance in environments of intense light.



  • Light resistance: 30K – 90K ohm
  • Dark resistance: 5.0M ohm
  • Max voltage: 150V DC
  • Max power consumption: 100mW
  • Dimensions: 5mm x 2mm



  • 10 x MG5539 Photoresistor / Light Dependent Resistor (LDR)
