Abstract:An air-coupled ultrasonic water gauge node based on ZigBee technology was designed.The self-transmitting-self-receiving ultrasonic ranging system with temperature compensation and wave-elimination filtering algorithm was realized by taking CC2430 as the core.The system was characterized by flexible networking,high precision,low cost,low power consumption and high reliability.It could be employed to solve problems in large-scale river model experiments such as multiple sections,multiple parameters,long running time,high requirements for synchronous and real-time measuring,which are difficult for the existing instruments.
Keywords:river model  ZigBee technology  ultrasonic water gauge node  temperature compensation  median filter
