A Study on Liquid Level Measurement and Control System Based on Single Chip Microcomputer

Introduces a method of using STC89C51 microcontroller as the control core, the system capacitance sensor for measuring and controlling liquid level. Through the analysis of field level condition, by using the capacitance sensor to detect the liquid level of a field physical quantity, and then detected information through the processing circuit, transmitted to the microcontroller, the use of computer technology, the level data collected in the field of real time signal processing. Through the application of the system, achieved the industrial level of indirect measurement, automatic control and management purposes.
