LDR Light Dependent Resistor Basics

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 different resistance value in day and night as given bellow

  • Daylight: 5000Ω
  • Dark: 20000000Ω

Application of LDR or Photoresistor

  • Camera Exposure Control
  • Auto Slide Focus
  • Photocopy Machines
  • Colorimetric Test Equipment
