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.
