12mm Light Sensitive Photoresistor LDR

Light Sensitive Photoresistor LDR - 12mm

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

The LDR sensor 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 day and night as given below:

• Daylight: 5000?
• Dark: 20000000?

Features

• It requires less power to operate
• Quick Response
• Easy to use
• Generate high current
