The title of the graduate design microcontroller-based water level detection and control system design, three metal rods into the water used to detect the signal, the conductivity of the water, can see that the water level changes. Under normal circumstances, the water level should be kept within a certain range changes, the water level does not exceed the stipulated upper and lower limits, in the event of a system failure, should be promptly cut off electrical power, and there should be sound and audible alarm signals of the light-emitting diode. Design System aimed the application microcontroller run automatically, so that the water level in the water tower always maintained within a certain range in order to ensure the continuous normal water. The design is based on AT89C51 microcontroller as the core components of the water tower water level detection and control simulation system designed to detect water level control, pr
