Water velocimeter and turbidity-meter using visible light communication modules
Baltimore, MD（2013）
Abstract
Traditionally, water turbidity can be measured based on the absorption or scattering effects. Water flow velocity can be measured based on Doppler frequency shift (DFS) estimation. In this work, we aim to provide a simple, robust, low-cost and accurate method for both measurements by using visible light communication (VLC) modules. Signal processing methods to extract the water turbidity and water flow speed based on the VLC transceiver modules are designed and implemented.
