Abstract
The study focused on the design and fabrication of an alternative low cost water level detector that measures the level of the water in a water container using a capacitive water level detector that measures the level of the water in a water container using a capacitive water level detector. The capacitive water level detector was made using a parallel plate capacitor, with galvanized iron as a material used for construction. Three setups, namely: (1) raw capacitor, (2) capacitor in PVC pipe, and (3) water isolated between plated, were evaluated for functionality by determining the relationship of the voltage across the corresponding capacitive element and the actual water level. For all setups, the firmware used to control the main circuit was written in Arduino and was uploaded in a gizDuino Mini 328 microcontroller unit. From these setups, it was determined that voltage across the capacitor if logarithmic and inversely proportional to the water level. Five equations relating voltage and water level were generated, with each equation corresponding to different ranges of water level. Among the setups, setup 3 produced the least average percent error of 2.8676%. Lastly, the total price of the materials used in fabricating the device was compared to the price of similar devices available in the market. The results of this study provided data that can be used for future studies on alternative capacitive water level sensing.
