Design and Implementation of Water Level Warning System Based on Single Chip Microcomputer
Abstract  With the improvement of science and technology, people's demand for quality of life is getting higher and higher, so automatic control system comes into being. As an integrated circuit chip with data processing capability, SCM has been widely used in production and life. This experimental device is based on the AT89C51 microcontroller, and the water level sensor is made based on the electrical conductivity of water to detect and warn the water level, forming a device for warning the pumping of water at low water levels and warning the stop of high water levels. It is also possible to manually control the liquid level. This kind of device has the advantages of low power consumption, simple and reliable circuit,  strong interference resistance, small size of circuit, and convenient operation. It can meet the needs of different people and has broad development prospects.
