MINIMUM TECH FEATURES:

• Diameter: 5 mm
• Number of Pins: 2
• Mounting Type: PCB Through Hole
• Dark Resistance: 1–20 MΩ
• Maximum Operating Temperature: +80°C

DESCRIPTION:

• The LDR-5MM-MODULE uses a photoresistor (CdS cell) that changes resistance based on ambient light intensity.
• The 5 mm compact form allows integration into small or space-constrained devices.
• Outputs a voltage proportional to the surrounding light level — ideal for analog inputs on microcontrollers.
• Features a simple two-pin connection for easy interfacing and low-cost circuit integration.
• Commonly used in light-activated switches, ambient light detection, and automatic brightness control applications.
• Can detect sunlight intensity for environmental monitoring or light-based robot navigation (e.g., line-following).
