water tank overflow sensor alarm working model explanation in english howtofunda

Making early warning working model, in this course introduces learners to the design and creation of simple, functional models that demonstrate how early warning systems work. Students will explore the science and technology behind detecting natural hazards such as earthquakes, floods, fires, or gas leaks using basic sensors and circuits. The course guides participants in building practical prototypes like vibration detectors, water level alarms, fire sensors, and gas detection systems with buzzers or LED indicators. Emphasis is placed on understanding the role of early warning in saving lives, reducing damage, and increasing preparedness. Using affordable materials and easy-to-follow methods, learners will combine science, engineering, and creativity to develop models suitable for classroom projects, science fairs, or community awareness activities. By the end, participants will gain both technical skills and awareness of the importance of early warning systems in everyday life. howtofunda
