LDR Photoresistor



A light-dependent resistor, alternatively called an LDR, is a variable resistor whose value decreases with increasing incident light intensity. It\u2019s common application street lamps, security alarms and any project that require light detecting capability.


  • Max working voltage of 150V
  • Light resistance at 10 lux is 8k ~ 20k ohm
  • Dark resistance at 0 lux is 1M ohm
  • Peak spectral response at 540nm

Package Included:

1 x LDR Photoresistor
