Abstract

A fringing Effect Field or FEF moisture sensor is the moisture sensor that used the fringing electrical field model. The performance of FEF sensors is typically evaluated based on their penetration depth, signal strength, measurement sensitivity and linearity. This paper presents two effects on the sensitivity of the sensor which are the electrode size (finger width) and number of ground electrode. The sensitivity is based on the capacitive value as the sensor is the capacitance based sensor. The simulation is carried out using FEMM tools as it can determine the value of the capacitance. The analysis is based on how much the finger width and the number of ground electrode may influence the sensitivity of the sensor. The finding shows the smaller the finger width the higher sensitivity or capacitance and the less number of ground electrode will reflect to capacitance increases.
