solar powered irrigation system working model for school science project exhibition howtofunda

Automatic street light working model, in this course teaches students how to build a smart lighting system that automatically turns lights on in the dark and off in daylight. This hands-on course introduces the concept of energy efficiency and automation through practical application. Learners explore how light-dependent resistors (LDR), sensors, and circuits detect changes in light intensity to control the flow of electricity. Using simple materials like LEDs, transistors, resistors, and power sources, students create a functional model that mimics real-world street lighting systems. The course also explains the working principle behind automatic control systems and their role in reducing electricity consumption and environmental impact. Ideal for science fairs and school projects, it encourages innovation, sustainability, and problem-solving while demonstrating how technology can make public systems more efficient and eco-friendly. howtofunda
