10mm LDR (Light Dependent Resistor)

Product Overview

The 10mm LDR offers the same fundamental functionality as its smaller counterparts but with a larger sensing head. This increased surface area allows for more stable readings in variable lighting conditions. Its resistance drops as light intensity increases, making it a reliable “analog eye” for your microcontroller. Whether you are building a solar tracker or an industrial light controller, the 10mm version provides a robust physical and electrical interface.

How to Use & Connections

• Increased Coverage: The larger 10mm head is easier to align with light sources in outdoor or large-scale projects.

• Standard Wiring: Typically used in a voltage divider circuit with a 10KΩ resistor to provide an analog voltage signal to an Arduino or ESP32.

• Durability: The larger epoxy coating provides better protection and heat dissipation during operation.

Technical Specifications

Key Features

• Enhanced Sensitivity: The larger surface area allows for better detection of subtle light changes in dim environments.

• Wide Dynamic Range: High dark resistance ensures very low power leakage in the absence of light.

• Breadboard Friendly: Fits easily into any standard 0.1″ pitch breadboard (like the MB-102 or 400-point).

• Versatile Application: Excellent for high-power switching circuits when paired with a transistor or relay.
