This paper presents the non-substrate interdigital capacitor level sensor. The interdigital capacitor level sensor is designed and fabricated to be two types that are the fabricated with an epoxy substrate and with none substrate. Each type is separated to be 6 models that are designed with difference dimensions of the width, the gap and the length of the hard copper (H04) lines circuit for comparing and obtaining the high linearity model. The fabricated with none substrate can sense the maximum capacitance of 877.56 nF that is higher than the maximum capacitance of the sensor with substrate of 341.12 nF. The higher range of the capacitance of the circuit with none substrate, provides the wide range to sense the water level with high accuracy that is suitable to develop to be the standard level sensor in the future.

W artykule zaproponowano nową koncepcję planarnego pojemnościowego czujnika poziomu. Do wykonania czujnik wykorzystano standardową technologią obwodów drukowanych. Otrzymano liniową funkcję przetwarzania ze współczynnikiem korelacji między 0.9782 a 0.9984.

This paper presents a study of a novel planar inter digital capacitor level sensor. It was design by using capacitor principle and they have been fabricated using standard single side on printed circuit board (PCB) fabrication technology. This experiment is carried out by using our sensors are different from the past IDC by adding finger beside the first finger of IDC. The value of capacitance is depending on length width space and increment the water. The linearity response with correlation coefficient (R2) was between 0.9782 to 0.9984. The results of the experiments provide an opportunity for further research in the development of low cost, small of sensor for measuring water level. The experimental also results show there is possibility of developing a sensor for water levels generally. A novel planar IDC level sensor has been fabricated to have better sensing performance. The advantage of this sensor is a very simple structure and inexpensive.
