Abstract: The fluctuation of groundwater level and reservoir water level is closely related to human’s social life. Currently adopted water level gauge usually results in inaccurate measurements. In order to reduce the adverse impacts caused by manual operation, we built an embedded remote water level monitoring system using B/S architecture to accomplish 24 hours real-time monitoring, data storage, and remote data download and inquiry with the measurement resolution reaching 1 mm and the measurement accuracy within 2 cm. The system can be used for single point monitoring, and also distributed multi-point regional monitoring. Experiments have proved that the present water level monitoring system could accomplish long-term stable water level observation, and could meet the demands of most water level monitoring fields.
