This research presents the application of soil nutrient sensors in electrical conductivity and pH level measurement of the water solution in the hydroponics system. The micro-controller was set to processes the raw sensor data and converts it into a readable format. The results revealed that the electrical conductivity was measured between 90-120 millivolts while the EC values were measured between 67 to 138 us/cm. To investigate the pH level, the electrical conductivity was measured between 43-60 millivolts which the pH level was 6.52-7.22. Moreover, it was noticed that the values from the sensors and the EC meter were inversely variation. It could be concluded that there are some potentials in applying soil nutrient sensors in electrical conductivity and pH level measurement of the water solution in the hydroponics system.
