Description

LDR  Light Dependent Resistors 20mm

This is a  LDR Sensor. A photocell (also called a photodetector, CDS or photoconductive cell) changes resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).

Specification:

• Light resistance: 10-20K Ohm
• Dark resistance:1-20M ohm
• Max voltage: 150V
• Max power:  100mW
• Maximum Operating Temperature : +800C (Approx.)

Features:

• Good Characteristic of Spectrum
• Quick Response
•  Epoxy or hermetical package
• Reliable Performance

Applications:

• Burglar Alarms
• Light Detectors
• Light Sensor
• Color Sensor
• Line Sensor
• OBJECT SENSOR
• Photo Switch
• Lighting Controls For Street Lamps
• Light Intensity Meters
