50pcs 5mm Photoresistor LDR Photo Light Sensitive Resistors

Description

Upgrade your light‑sensing projects with the 50pcs 5mm Photoresistor LDR Photo Light Sensitive Resistors. Designed for precision and reliability, these compact LDRs deliver consistent performance in a wide range of electronic applications, from hobbyist experiments to professional prototypes.

Product Overview

Each 5 mm photoresistor converts ambient light into a variable resistance, enabling seamless integration into circuits that respond to brightness changes. Packaged in a convenient bulk set of 50, you’ll always have spares on hand for testing, replacement, or large‑scale builds.

Key Highlights

• High sensitivity to visible light for accurate detection.
• Compact 5 mm (Ø) size fits tight PCB layouts and breadboards.
• Wide resistance range: 1 kΩ (bright) to 10 MΩ (dark).
• Fast response time for real‑time light tracking.
• Stable performance across temperature variations (‑40 °C to 85 °C).
• Bulk pack of 50 pieces – perfect for prototyping and production runs.
