| Abstract: | Introduced the development of a networked intelligent liquid detector which used two ultrasonic detectors as detect probe,the liquid detector has the function of temperature compensation and self-diagnostic.PIC18F258 MCU made by Microchip company was the core part of the detector.The ultrasonic detector gave off pulse signals,and the back signals were received and converted into pulse voltage,PIC18F258 MCU calculated the distance according to the signal transmission time.The system can be detected and modified by itself based on the different data between the two ultrasonic detectors and the fastest data-transmission rate can be achieved at the aid of the software. |
| Keywords: | liquid level detector ultrasonic detector networked detector |
