A vibrant cartoon with bright colours and smooth animation. Scene 1: Female students in a classroom work on computers. Scene 2: The classroom temperature rises, and the students begin feeling hot. A clear temperature display changes from 28° → 31° → 35°. Scene 3: An Arduino connected to a temperature sensor detects the rising temperature. A responsible staff member intervenes, and a warning appears: " Warning: High temperature." Scene 4: An alert notification arrives on the phone of the safety and security officer, showing the temperature issue. The temperature then decreases from 35° → 28°, and the female students comfortably return to their computer work.
