Abstract

The cleaning company "VETkanaal" requested a sensor system that measures the thickness of a grease layer within kitchen extraction ducts independently and is able to send this to an online platform. The goal of this project is to find an acoustic implementation of the sensor and be able to apply it. It appeared that measuring a shift in resonance frequencies of a plate with varying amounts of grease is the best solution for estimating the thickness of a grease layer. Afterwards, a hardware implementation was made. The conclusion of this report is that an acoustic measuring principle is certainly possible. The first tests of trying to implement such a system were moderately successful.
