Light Dependent Resistor (LDR) 8mm

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
