Product Description:

The Light Dependent Resistor (LDR), also known as a photoresistor, is an essential electronic component that changes its resistance based on the intensity of the ambient light falling on it. This 5mm LDR is highly sensitive to light, making it perfect for use in various light-sensitive applications. Whether you’re working on automated lighting systems, solar energy projects, or light-sensitive triggers, this LDR offers precise and reliable performance.

This LDR can be used in a range of electronic circuits and is ideal for Arduino, Raspberry Pi, and other DIY projects. Its compact 5mm size ensures that it fits easily into even the smallest projects while offering excellent sensitivity to light, making it a must-have for both hobbyists and professionals alike.

Key Features:

Compact 5mm size – Perfect for small projects and tight spaces.
