Abstract
In order to realize water level monitoring and control, the controller of water level detection system is designed and manufactured with STC89C52 as the core control chip. This paper introduces the working characteristics of the core control chip STC89C52, describes the working principle of the system electrical appliances, and expounds the design and debugging process of the controller of the water level detection system. A scheme of controller for water level detection system using single chip computer and pressure sensor is proposed. The hardware and software involved are tested comprehensively. The results show that the design can successfully realize the detection and control of water level, and has a certain practical application prospect.
