“…Many methods are provided to build and develop hydroponic systems. According to [3], the conventional method needs more time and manpower to control and monitor hydroponic systems where everything should have manually. The pH water solution takes a time to read pH value which is needed to periodically monitor and balance a required value of maintaining a quality of the nutrients solution.…”

This paper presents an automated hydroponic system, where a Raspberry Pi is used to maintain the pH level in the presence of time-delay. The Ziegler-Nichols method is used for tuning the parameters of the PID controller. Moreover, a Web user interface is developed to control, monitor, and record the pH level, temperature, and water level. Experimental results illustrate that the required pH level can be attained by the proposed control scheme.

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.
