01 — About

What it does

The LDR Sensor Light Dependent Resistor is a photoresistor whose resistance decreases as light intensity increases. Available in 3mm and 5mm sizes, it is commonly used in automatic lighting, light meters, and sensor circuits.

Key features

  • 5mm package
  • Photoresistive element
  • Wide resistance range
  • Fast response time
  • Low cost

Good to know

  • Use in voltage divider with fixed resistor
  • Response time: ~10ms rise, ~100ms fall
  • Not precise for lux measurement
  • Sensitivity varies with temperature
