LDR Photoresistor, GL5516, 90mW, 150VDC, 4 Pcs/Pack

Light-dependent resistors or photo resistors are a staple of electronics. If you need a way to sense the level of ambient light then there is no easier way to do it. As the light on the sensor increases then the resistance across the two leads decreases.

• Spectral Peak: 540nm, Light Resistance (10Lux): 5-10 Kohm, Dark Resistance: 0.5 Mohm
• Resistance Illumination: 2
