LDR Stands for Light Dependent Resistor and its Resistivity varies with Incident Electromagnetic Radiations so, its resistivity is a function of Incident Electromagnetic Radiations or light. Other names of LDR are photoresistor, Photoconductor, Photocell, and photo conducting cell

LDR is made of Semiconductor materials with high Resistance like Silicon or Germanium. It is a light-sensitive device, so this resistor has a different resistance value in day and night as given below

  • Daylight: 5000Ω
  • Dark: 20000000Ω
  • It requires less power to operate
  • Quick Response
  • Easy to use
  • Generate high current
  • Camera Exposure Control
  • Auto Slide Focus
  • Photocopy Machines
