| Abstract | This paper presents the water level sensor fabricated from a printed circuit board. The copper traces of a printed circuit board as periodic fingers and capacitance between parallel fingers varied according to the water level. The change of capacitance can be measured and converted to a water level by a microcontroller. The output signal of a water level from a microcontroller transmitted to a computer or other devices are compatible with the RS-232 standard. The experimental results show that the water level sensor has linear relation with R2 = 0.9992 and maximum error is 2.3 %FSO. In addition, this sensor need low energy. |
