GPRS based river water level monitoring and measuring system

According to the current status for measuring water-level of the river, a river water-level remote monitoring system has been designed, which consists of a water-level sensor, a single chip microcomputer, a wireless module and user terminals. The designed contact type water-level sensor based on a simple principle with a high performance-cost ratio, has eliminated the shortcomings of the current sensors, which must be placed under the water with difficulty of water proof. The water level information collected can be real-time transmitted with signal of GPRS to the server terminal, users can easily transfer real-time data and history of data record from the server terminal. The experimental results show that the system can work stably, with a high accuracy, low cost, and easy to market.
