ABSTRACT: In this paper a two electrode sensor for measuring water conductivity for the hydroponics system is
presented. The sensor is designed to measure the conductivity of nutrient solution which is in the range of millisiemens
(mS). These electrodes are used to regulate the nutrient in hydroponics solution according to the plant’s requirement.
The automatic hydroponic system is based on low cost ARM processor that monitors and control the need of
hydroponics plants. Automatic hydroponics system will boost the production by controlling the different parameters.
