“…al [20], presents a literature survey of hydroponic systems and smart technologies that can be used to improve the performance of such systems. Kaewwiset and Yooyativong [9] investigated the relationship between the electrical conductivity (EC) and the pH of the hydroponic nutrient mixing system. In [21], potassium acrylate is proposed for hydroponic substrates, because of its water-absorbent nature and the fact that it is biodegradable.…”

“…Nutrients in a good hydroponic system must contain the optimum level of; oxygenation, salinity, pH, and conductivity of nutrient solution [8]. The hydroponics fertilizers contain six essential nutrients: N, P, S, K, Ca and Mg, which are fed to the plants in form of mutual ratio of anions: NO − 3 , H 2 PO − 4 and S O 2− 4 , and the mutual ratio of cations K + , Ca 2+ and Mg 2+ [9]. Several growing medium like a wood chip can be used with water to form a hydroponics system [10].…”

The explosion in human population has left researchers scrambling for solutions on how to feed the world. Furthermore, rural-urban immigration has on the one hand left the farms in the rural areas devoid of farmers and on the other hand has left the urban areas over-populated. Hydroponics is a form of agriculture where crops are grown without soil. This technique allows the farms to follow the farmers to the urban area. In addition, the fact that no soil is needed, allows hydroponic system to be stacked vertically (also known as vertical farming) to save space. The final frontier in hydroponics is automation. It will allow one farmer to work more than one job and cultivate more than one farm simultaneously. This paper provides a comprehensive survey on smart hydroponic system developed to date.

“…Hydroponics farming ( Tagle et al, 2018 ) is an intelligent way of growing crops that yields high-quality organic plants in a limited space without using soil and does not expose them to external disasters, and not causing any environmental pollution. The hydroponic food production method is becoming more popular for cultivating crops, especially for urban people who can grow plants on balconies or rooftops ( Kaewwiset & Yooyativong, 2017 ).…”

“…The threshold range of pH values of hydroponics plants is mostly from 5.5 to 6.4. The pH value above or below the predetermined threshold can cause nutrient deficiencies that reduce productivity ( Kaewwiset & Yooyativong, 2017 ). The electrical conductivity (EC) is proportional to the number of ions dissolved in the explanation.…”

Background The primary objective is to address the specific needs of plants at different growth stages by delivering precise nutrient concentrations tailored to their developmental requirements. Challenges such as uneven nutrient distribution, fluctuations in pH and electrical conductivity, and inadequate nutrient delivery pose potential hindrances to achieving optimal plant health and yield in hydroponic systems. By overcoming these challenges, the hydroponic farming community aims to enhance the accuracy of nutrient dosing, streamline automation processes, and minimize resource wastage. Hydroponics, a cultivation technique without soil, facilitates the growth of organic vegetation while concurrently minimizing water use and eliminating the necessity for pesticides. In order to achieve effective cultivation of hydroponic plants, it is essential to maintain a controlled environment that encompasses essential factors such as temperature, carbon dioxide (CO2) levels, oxygen availability, and appropriate lighting conditions. Additionally, it is crucial to ensure the provision of vital nutrients to maximize output and productivity. Due to the demanding nature of a hydroponic farmer’s schedule, it is necessary to minimize the amount of time dedicated to nutrient management, as well as pH and EC adjustments. Methods In order to determine and deliver the proper amount of vital nutrients, such as nitrogen, phosphorus, and potassium, based on the plant growth stage, we presented an automatic hydroponic nutrient estimator in this system. We noticed that the plant’s nutrient consumption varies depending on its stage of growth according to plant psychology. Four peristaltic pumps with the necessary sensors are controlled by an Arduino board in the suggested system. Both filling and draining the water are done using each pump. To identify the plant stage, we apply the Plant Growth Stage Identification algorithm to encompass the seedling, vegetative, flowers, and fruit stages. Results The experimental results reveal that the Growth Stage Identification algorithm obtains 97.5% accuracy for the first 5 weeks with 1,715 ppm of nutrition ingestion, identifying the vegetative state. The flowering stage is identified with 97.5% accuracy in the 6–9th week with 2,380 ppm of nutrition consumption, and the fruiting location is determined with 99.4% accuracy in the last 10–15th week with 2,730 ppm of nutrition consumption.

“…Recall that pH is a measure of the hydrogen ion concentration of a solution. An acidic solution has a higher relative number of hydrogen ions which its substances dissociated to release hydrogen ions or react with water to form hydrogen ions while the alkaline solutions have the higher corresponding number of hydroxyl ions which its elements dissociated release hydroxyl ions or react with water to hydroxyl ions [8][9][10].…”

<span>A hydroponics plant can grow healthily with sufficient nutrient, temperature, light, humidity as well as pH level that is indeed vital in ensuring the plants will absorb maximum nutrient elements required. This paper presents automated monitoring and controlling pH levels for the hydroponic cultivation technique. In this study, automated monitoring and controlling of pH levels are developed specifically for the hydroponic cultivation technique. There are three main methods that involved in the development of the system namely hardware, programming and functionality test. Firstly, users need to set the maximum and minimum pH levels as required by the plant. Then, the pH sensor will monitor the real-time pH level of the water. A syringe pump that contains a pH up solution (alkaline) and a pH down solution (acid) will drip the solutions to neutralize the water content if the water pH level is not within the stated ranges as set by the user. Results showed that the automated monitoring and controlling pH levels were successfully developed and functionality was tested and confirmed as desired. The syringe pumps responded perfectly upon changes of the water pH value based on the validation done that showed 100% accuracy of the syringe pump responds. </span>
