This design take the water tank water supply as a model, uses in carries on the survey to the water tank fluid position signal to monitor the record. The liquid level measurement device base on MCU is widely used because of many characteristics such as high measurement accuracy, good repeatability, low power consumption and long useful time. When we study Scientific Outlook on Development thoroughly, the design of electronic aid should include the thought of sustainable development. So, beyond the liquid level measurement device based on MCU, expand the functions of real-time monitoring, data acquisition, serial communication. Through the new functions, the scientific method of the liquid level measurement could be combined with Statistical Science, be used to manage the water resources reasonable, reduce energy consumption. This thesis introduces the design process of the liquid level control system by several parts as system schema, the design of hardware circuit, the software of host computer and system software, ultimately achieved the level of real-time measurement and monitoring. Finally, the paper summarizes the problems and solutions of the design process, describes briefly the method of data processing, and leads to ideas of the further design and development.
