Abstract

In engineering and experiment, it is often necessary to accurately measure water level, which can be used for flood control and has a significant impact on people's lives. At present, the commonly used methods are image acquisition and recognition, but they are vulnerable to interference, and the accuracy rate is low. In order to reduce interference and improve accuracy, a new technology based on capacitance sensing is adopted. When the water level changes, the parasitic capacitance will change. This change can be detected by a high-precision sensor and converted to the water level value.
