Design and Implementation of Wireless Water Level Monitoring System Based on ZigBee;

To address problems in traditional water level monitoring,this paper developed a water level monitoring system based on G20 GPRS module,integrating AVR Atmegal 6 control chip with GPRS module to form an automated wireless transmission system,which can transmit data of water level sensor through GPRS wireless module to remote data centre console for analysis.

The Water Level Monitoring System is essential for a reliable operation of a water power station.

Study on Intelligent Water-Level Detective Monitor Based On UPSD3454 Single Chip Computer;

In this paper, the status of Water-Level Detective Monitor at home and abroad was set forth and the composition and structure of the GSM system was given an introduction in detail.

Design and application of mobile wireless digital water-level monitoring station;

Automation monitoring instruments have been widely used in groundwater level monitoring,but scientific sampling interval of the instruments should be paid attention to because of data redundancy,lack of money and waste of resources.
