Pack of 6 LDR Light dependent resistor Light sensor 5mm Photoresistor

Sepcifications

Size: 5mm head diameter with two flexible pins for easy breadboard or PCB mounting.
Light Behavior: High light = Low resistance (usually a few hundred ohms to ~20 kΩ). 
Darkness = High resistance (usually 1 MΩ to several mega-ohms).
Material: Typically constructed using Cadmium Sulfide (CdS) semiconductor film.
Spectral Peak: ~540 nm (highly sensitive to visible light, matching the human eye).
Max Voltage: Up to 150V DC.Power Dissipation: 100 mW.
