Communicating vessels for low-cost water level monitoring

There are many factors cause error of the reading of resistive sensors for monitoring water level influenced by several factors. One of them is the shape of the water tank. This study aims to improve the reading of resistive sensors to the shape of water tanks, regardless its shapes and volumes. It can be achieved by utilizing communicating vessels. The resistive-based on voltage divider sensor, in the form of two conductive wires dipped in water. This water level measurement uses STM32F103C8T6 as a data processing control. It serves a better capability for the sensor to read water levels in two tanks of different shapes and volumes. The resistive sensor can read the water level with an average error of 1.11 percent.
