A wireless sensor module consisting of accelerometers, gyroscopes and a microcontroller detects the rotations and accelerations of the module when placed in a hydraulic environment. The device is to be used to detect sedimentation in rivers by processing the motion sensor data stored within it. Inertial navigation algorithms have been programmed into the device to reproduce its trajectory in 3 dimensions. The device called the `smart sediment particle' is wirelessly charged using inductive power transfer technology, and powered by super capacitors, which has proven successful. The device is based purely on commercially available sensors which provide reasonable accuracy for the purpose of detecting sedimentation.
