- The water level alarm adopts the mechanical or magnetic inductive methods to set the water level alarm.
- Theory: when water added to the cup, the water level goes up and the suspending ball is raised up. The micro-switch previously pressed by the universal rod will be loosened. The normally close contact recovers to close and the circuit gets through. The buzzer and LED starts to work.
- From this work we can understand the application of micro-switch and the simple automation and control technology.
- The descendable thinking:
1. Change this work into water shortage alarm.
2. Add another pump and make it stop pumping water when the water is full.
- Provide for yourself: a screwdriver, a scissor, a lighter, etc.
