In order to measure the concentration of different liquids, a new type of sensor is used to detect the small capacitance change. When a thin copper sheet is inserted into the solution, when the liquid concentration changes, the capacitance of the copper plate to ground will change. Fdc2214 is used to sense the change and convert it into digital quantity, which can be measured by various microprocessors through IIC output.
