Overview

The 20mm Photo Resistor (LDR – Light Dependent Resistor) features a large sensing surface that offers enhanced sensitivity to light, making it ideal for applications requiring precise detection of ambient light intensity. This sensor’s resistance varies inversely with the light exposure, providing reliable performance in both hobbyist and industrial projects.

Description

Key Features:

  • 📐 Large Diameter: 20mm sensing surface for improved light detection accuracy.

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

  • Fast Response Time: Quickly responds to changes in lighting conditions.

  • 🔄 Robust & Durable: Suitable for indoor and outdoor environments.

Typical Applications:

  • Advanced automatic lighting controls (e.g., streetlights, floodlights)

  • Precision light intensity measurement devices

  • Solar tracking and energy management systems

  • Security and alarm systems triggered by light changes

  • Microcontroller projects (Arduino, Raspberry Pi)

Specifications:

  • 📏 Diameter: 20mm

  • Maximum Voltage: 150V DC

  • 🔋 Power Rating: 100mW

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

  • 🌙 Dark Resistance: Approximately 1MΩ

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

  • Response Time: Rise and fall time less than 30ms

This LDR sensor is an excellent choice when you need enhanced sensitivity and reliability in light detection for sophisticated lighting and sensor applications.
