This model demonstrates an automated flood prevention solution using simple sensors and motor mechanisms. When rainwater is detected, the system activates a submersible pump to drain water from the basement, thus preventing flooding. This model is especially useful for urban smart homes, low-lying building basements, and monsoon-prone areas. The project combines basic electronics with environmental … Read more
