An LDR (Light Dependent Resistor), also known as a photoresistor, is a light-sensitive component that changes resistance based on the intensity of light falling on it. When exposed to bright light, its resistance decreases, and in darkness, its resistance increases, making it ideal for automatic light control applications.
Key Features:
✔ Highly Sensitive to Light – Resistance varies with light intensity.
✔ Low Power Consumption – Ideal for battery-powered circuits.
✔ Fast Response Time – Quickly adapts to changing light conditions.
✔ Compact & Easy to Use – Can be integrated into various electronic projects.
Common Applications:
🔹 Automatic streetlights
🔹 Light-activated alarms
🔹 Smart home lighting systems
🔹 Solar garden lights
🔹 Camera exposure control
