DIY – Street Light Electricity Kit – Tested & Verified (Educational projects and learning DIY kit)

Product Description The DIY Automatic Street Light Kit is an educational model that demonstrates the concept of smart city automation. By utilizing an LDR (Light Dependent Resistor), the system can automatically detect the transition from day to night. When the sensor is covered or ambient light levels drop, the circuit triggers the LED street lamps to glow. This "tested and verified" kit is perfect for school science fairs, teaching the basics of sensor-based logic and energy conservation.

Key Features

• Automated Logic: Replicates real-world street lighting systems that activate at dusk and deactivate at dawn without human intervention.

• Sensitive Light Detection: The high-quality LDR sensor responds accurately to subtle changes in light intensity.

• Dual-Lamp Setup: Includes two vertical street lamp posts, allowing students to build a realistic miniature road scene.

• Plug-and-Play Assembly: Simple wiring instructions (Red-to-Red, Black-to-Black) make this kit accessible for beginners and young hobbyists.

• Interactive Testing: Comes with a "Night Cap"—a specialized cover used to simulate darkness and instantly test the sensor's response.

Technical Details

• Dark Sensing Principle: In high light, the LDR has low resistance, keeping the LEDs off. As it gets dark, the LDR's resistance increases, allowing the transistor to switch on the current to the lamps.

• Portability: Operates on a single 9V battery, making it a self-contained unit for display on desks or project boards.

• Modular Components: The LEDs are mounted on pre-shaped yellow poles for a professional and uniform appearance.
