LDR Project Working Model | Day Night Sensor Circuit

LDR Working Model

Explore the fascinating world of light detection with this practical LDR (Light Dependent Resistor) Working Model. This educational tool is perfect for school science projects, physics experiments, and hands-on learning experiences. By demonstrating how light intensity influences electrical circuits, this model provides a clear understanding of light sensors’ applications in everyday technology.

Components Used:

• Battery (9V)
• Transistor (547B)
• Resistances (200k and 470 ohms)
• LDR Sensor
• LED

How It Works:
The LDR sensor’s resistance varies based on the intensity of light it receives. In bright light conditions, the resistance of the LDR decreases, allowing the current to bypass the LED, causing it to remain off. As the light level drops, the LDR’s resistance increases, allowing current to flow through the circuit and illuminating the LED. This setup is perfect for demonstrating light-sensitive circuits used in applications like night lamps or automatic streetlights that activate when it gets dark.

Applications:
– Demonstrates the principles behind streetlights that turn on automatically at night.
– Useful for explaining light sensing in alarms, electronic devices, and energy-saving technology.
– Great for interactive learning in science classes, workshops, and exhibitions.
