GL5516 5mm LDR Sensor Photoresistor Photo Cell 5-10K

5mm LDR Sensor Photoresistor (GL5516) is a light-sensitive resistor that changes its resistance based on the intensity of light falling on it. It is widely used in light detection and control circuits.

This is a small LDR which can be used for making a light sensor, color sensor, object sensor, line sensor, etc .

Key Features of GL5516 LDR:

• • Photoresistor: Resistance decreases as light intensity increases.
  • Compact Size: 5mm head diameter, suitable for small spaces.
  • Cost Effective: Ideal for mass applications and educational projects.
  • Passive Component: Requires no power supply to function.

Technical Specifications:

• • Model: GL5516
  • Head Diameter: 5mm
  • Dark Resistance: ≥ 1MΩ
  • Light Resistance: 5KΩ to 10KΩ (at 10 Lux)
  • Max Voltage: 150V DC
  • Power Consumption: < 100mW
