International Journal of Computer Applications (0975 – 8887) Volume 175 – No. 34, December 2020 37 Plant Health Monitoring System using IoT Chonmoy Dhar Dipto Department of CSE American International University Bangladesh Shipon Ahammed Sohan Department of CSE American International University Bangladesh Md Manwar Hossain Department of CSE American International University Bangladesh Golam Rabbi Khan Department of CSE American International University Bangladesh Rifat Tasnim Anannya Department of CSE American International University Bangladesh ABSTRACT The Internet of things (IOT) actually refers to the interconnec- tion of the smart devices to collect data and also to make intel- ligent decisions. Used to develop numerous applications of Internet of Things technology, this paper combines the appli- cation of objectionable designs and greenhouse prototypes with IOT to adjust system parameters and monitor system status from anywhere on this earth. Here our task is we can’t monitor the health condition of the plants. So we have to mon- itor the health condition of the plants completely. There are some environmental parameters like temperature, light inten- sity, humidity, soil moisture which has effects on the plant conditions. We will check how these parameters affect our plants health condition. Informations will be sent towards the arduino and arduino will sent those data in a cloud platform. From stored sensor value users can check if there are any deviations in stored sensor value through smart phone. Any deviation means an alert message will be sent to the user. That’s how we are going to monitor the health conditions of our system. By knowing these environmental conditions we can know what is the need of our plants and we can take ef- fective steps than. Keywords IOT, Health, Ubidots, Plants, Condition Monitoring, Arduino. 1. INTRODUCTION The Internet-of-Things simply known as IOT is a network of interconnected objects embedded with electronics, software and sensors. In the last few years, IOT devices are gaining burgeoning popularity on consumer electronics market. IOT technology is playing an effective part in advancement of various domains of our everyday life including industrial automation, transportation, energy systems, and healthcare etc. Many researchers there can be maximum of 18billion IOT devices by the year 2022 [1]. For the use in future in most of IOT systems, data which are collected is stored in a central- ized server system [2]. From smoke detector system to the door lock system IOT has made life easier and smarter for the people. We can also give the example of the nest thermostat where we can adjust the temperature remotely. To do that wifi is connected with the thermostat. So because of this utility bills declined a lot. These are some examples of the IOT. From these we can say that IOT is making our life more com- fortable. In this paper we will discuss about the green house monitoring system in IOT. Green house monitoring with the system has played a great role in the agricultural sector. By using IOT agricultural sector has greatly improved. In the green house monitoring system plants health has to be moni- tored quite efficiently. Otherwise the outcome won’t be good enough so we have to make sure that many environmental parameters in the green house system is monitored by an IOT system so that plants health remains fresh. 1.1 Background Study A high comparative humidity which is above 80-85% must be avoided so it can expand the occurrence of disease and can hamper the plant development [3]. So, for betterment of the crops humidity should be checked regularly. An implementa- tion of a novel methodology of physical parameter monitor- ing, data display, data integration to the cloud, alert generation and predicting the future values are done with the help of MATLAB analysis [4]. Thus, to solve all such problems, it is necessary to build an integrated system that will take care of all the factors that affect such productivity at each stage; har- vesting and harvesting essential important elements for exam- ples temperature, humidity, carbon dioxide deficiency and plant growth have affected productivity at the end of cultiva- tion. [5]. Certain important factors such as temperature, hu- midity, light and the level of carbon dioxide has an impact on the productivity of plant growth [6]. As there is heavy rainfall in japan slope failures are quite common in there. So steps need to take about this matter so that these things don’t occur during rainy season. Soil moisture and groundwater levels are monitored using the intensity and propagation of reflected ultrasonic waves [7]. Smart farming is very important due to global warming. Real time monitoring of environment and water management is an important issue to consider in smart agriculture. [8]. the use of wireless sensor network; Will pro- duce great quality farm products in all seasons with unique power source distribution, monitoring valve and switch opera- tion and remote area control skills in agriculture. [9]. There are so Many agricultural systems which need irrigation. The evolution of distributed in-field sensor-based site-specific irrigation systems gives the edge to increase yield and stand- ard in time of saving water, but there are challenges like the absolute combination of sensor fusion, information interface, irrigation control, communication and software design. [10]. Through this it provides a remote sensor monitoring frame- work using GSM and GPRS innovations that may be an early part of e-farming productivity. [11]. The main target of this creating in e-agriculture is to obtain awareness, use and moni- toring of runners. [12]. 1.2 Problem Statement Plant health monitoring is quite important for agriculture. If
