"The document "Ultrasonic Liquid Level Measurement System Based on Single Chip Microcomputer.pdf" introduces the basic principles of ultrasonic ranging and system diagrams, provides ultrasonic transmitter and receiver circuits, and explains how to improve the accuracy of distance measurement through the elimination of blind spots and the sampling of environmental temperature. By utilizing the relationship between distance and time in ultrasonic transmission, the system uses an 8051 single-chip microcomputer for control and data processing, and designs a precise ultrasonic liquid level detection system that can accurately measure the distance between two points. The system is mainly composed of ultrasonic transmitter circuit, ultrasonic receiver circuit, single-chip microcomputer control circuit, environmental temperature detection circuit, and display circuit. The designed ultrasonic liquid level detection system was tested on liquid surfaces, and the environmental temperature at that time was collected to obtain an accurate speed, from which the liquid level distance was calculated. This system has the advantages of easy control, reliable operation, and high measurement accuracy, and can real-time monitor the liquid level.
