Hydroponics Cultivation Using Real Time Iot Measurement System

The concept hydroponic cultivation is performed in greenhouses or in various plat factories. This sort of cultivation is generally evaluated with pH and electrical conductivity. It may not provide complete information regarding any imbalance that is encountered in cultivation process. This causes poor yield or wastage of resources Thus, to overcome these limitation IoT measurement system has to be implanted in this cultivation process, where sensors and actuators may measure the corresponding reading when need and given to man power. Therefore, imbalance in attaining nutrients is eliminated by constant monitoring of resources towards plant cultivation. This facilitates farmers to handle the nutrients issues that are encountered in cultivation. The performance measurement of the system developed was computed with feasibility of IoT system for automatic measurements. The outcomes of the systems are computed and validated for further processing. Some specific measures are considered where there is no specific relationship among standardized analysis. The sensitive responses have to be examined and analyzed.


Introduction
In this revolutionary world, healthier life can be achieved only when fresh and non-pesticides based foods has to be consumed [1]. Fruits and vegetables are considered to be healthy only when it should not be contaminated with chemicals and it should not harm body when provided to pesticides like over and so on [2]. In real world scenario, it is not concluded that a human is consuming a healthier food without any chemicals or pesticides in it. Various reports have stated that there is death due to the inclusion of pesticides over the plants [3]. Generally, people who died of pesticides are agricultural workers or farmers with an age group of 15-30 years old [4]. Indeed, conventional way of planting 2 also has some deficiency. Initial one is origin of diseases and pests [5]. Next, various forms of plants needs some land suitability for farming. Next, area of cultivation with soil source is directly influenced by amount of vegetables which is generated [6]. Next, fertilizers use and water are lesser effectual. Weaknesses are preliminary form of hydroponic development based farming method.
These are automated systems that may provide nutrients on timely basis for regulating hydroponic with growth rate of 50% which s faster than soil [7]. Nutrient solution based conductivity is based on boosting plant growth and using controllers for it. Conductivity measurement in system is a form of electrode [8]. Nutrients amount requires manual computation and it should be stored in processor. This will be compared with amount of nutrients and computed manually. If needed lesser, pumps may turn on automatically to assist nutrients to appropriate value [9]. Finest solutions are attained by managing conductivity and nutrient solution with pH. It plays an essential role in absorbing every element during planting. With nature cycle, plants are in need of source for photosynthesis, light needed for plant measure is light integral. It may shows various responses to diverse light spectrum. To model a growing chamber for plants, there is a necessity of nutrient solution, climate and light. OpenAg source has been launched to construct food computer, server for maintaining plants [10]. Here, construction of automation system for hydroponic is done with maintenance of pH and conductivity of nutrient solution, controlling light, environmental monitoring like humidity, temperature, CO 2 ,pH and so on. To construct these sorts of systems that may functions with numerous processes. There are diverse of available RTOS, freeware and so on.
The remainder of the work is organized as: Section II is literature review, Section III is research methodology, section IV is numerical results and discussion. Section V is conclusion with future research directions.

Literature review
This section discusses about the background study that are related to hydroponic cultivation process. In [11] author reused nutrients for growing as a source of cost reduction and reducing environmental causes over hydroponic system. Electrical conductivity and pH values are monitored to compute status of nutrients provided to plant production. Author in [12], investigates the nutrient imbalance ratio and periodical adjustments that are introduced and appropriate intervals are considered. Use of periodical

Results and discussions
This section explains the numerical results and discussion of proposed model. The simulation was done with MATLAB simulation environment. The comparison of various concentrations is done in this section which is discussed in section given below. The modelling of IoT based monitoring system may be monitored resourcefully in concentration with Ca, NO3,and K in hydroponic solutions with appropriate level of sensitivity. However, system may be reacted with changes in ion concentration by reacting to treatments, salts and replenishment. The outcomes may demonstrate the system is more feasible for IoT based monitoring of diverse concentrations of K, Ca and No3 in hydroponic solutions. Table I depicts the system specifications of proposed models.   analyzed. The proposed model is considered to be more feasible. This can be implemented in various cultivation processes. The tested results are satisfactory and capability of this system is more effectual. In future, this system is implemented with various concentrations at various stages of crop cultivation.

Conclusion
This investigation concentrates on hydroponic cultivation in which crops are grown without the soil usage. However, nutrients from soil are provided directly to various water reservoirs. Nutrients that are needed for plants are added by proper measurements. Here, plants may attain essential nutrients from water as equal to that of soil. With the adverse growth of IoT and its characteristics this process is turned to be automated. Data that are gathered from this approach is processed and given to cloud for storage purpose. Also, mobile applications plays crucial role in this process. The growth of plants is monitored constantly from the sensors used in hydroponic system. Thus, this system can be used under any environmental conditions and operated through applications.
