In the past, many of the tanks are operated by the staff to operate, so that artificial means a lot of drawbacks, such as the water level control, water tanks at all times to monitor the environment, and so on the night of monitoring, the operator slightly negligence, or damage to the Summary of the monitoring device will bring irreparable damage will be even more serious crisis in production, such as the personal safety of staff. Therefore, control of water tanks, if the use of sophisticated and can totally be run in strict accordance with the provisions of the automated production system that can maximize the chances of avoiding accidents, but also save resources and can effectively improve the efficiency of production.  The purpose of single-chip system design is the application of single-chip control technology, to 8051 as the core to control the water level in water tanks, and implementation of the alarm and manual, automatic switching function. The system is easy to operate, good performance, more in line with t
