Function

The seat mat is a plastic mat filled with silicone. The silicone in the seat mat affects the pressure sensor. In the pressure sensor are two metal-coated
ceramic discs mounted close to each other. The disc closest to the pressure connection is thinner and bends with exerted to pressure. The capacitance
between the metal coatings on the discs will hereby change depending on the pressure. Integrated in the sensor is a circuit that converts the capacitance
into an analogue voltage.
