Overview

The 10mm Photo Resistor (LDR – Light Dependent Resistor) is a highly sensitive light sensor that changes its resistance based on the amount of light it detects. It is ideal for a wide range of light sensing applications, from DIY electronics to industrial automation systems.

Description

Key Features:

  • 📏 Large Sensing Surface: 10mm diameter for improved light detection.

  • 🌞 Light-Sensitive Resistance: Resistance decreases as light intensity increases.

  • Fast Response Time: Quickly detects changes in light levels.

  • 🔄 Wide Operating Range: Works in various ambient light conditions.

Applications:

  • Automatic lighting systems (street lights, garden lights)

  • Light intensity meters

  • DIY Arduino and Raspberry Pi projects

  • Solar tracking systems

  • Alarm systems and light-based sensors

Specifications:

  • 📐 Diameter: 10mm

  • Max Voltage: 150V DC

  • 🔌 Max Power Consumption: 100mW

  • 🌡️ Operating Temperature: -30°C to +70°C

  • 🌙 Dark Resistance: ~1MΩ

  • 🌞 Light Resistance (10 Lux): ~10kΩ

  • Response Time: Rise time < 30ms, fall time < 30ms

This LDR is a compact, cost-effective, and reliable component for detecting light levels in a variety of projects and systems.
