The authors advocate that the proposed system will help farmers to settle on the correct choice, increase better yield and financial advantage.(Rao & Sridhar, 2018) Developed a Precision Agriculture (PA) irrigation system with low circuitry complexity that uses two sensors (temperature and moisture) interfaced with an IoT based Raspberry pi microcontroller. The main aim of the system is to improve crop productivity with low water consumption. The two sensors are utilized to control the irrigation system. The system sets threshold voltages considering the past soil moisture and temperature readings. They may be varied according to the crop and plantation. Through this approach an irrigation system can be completely automated. The developed system is said to help farmers with real time information about their lands and crops in order to make the right decisions. The said system also advantageous as it optimizes the usage of water fertilizers and maximizes crop yield while also helping in analyzing the conditions of the field. The authors further go on to state that their work may be extended by introducing machine learning algorithms to process the data and minimize the hardware complexity.(Changmai, Gertphol, & Chulaka, 2018) Developed an IoT based Smart Hydroponic farm to compare its merits over the regular hydroponics farms. The authors chose lettuce for testing. The developed smart farm monitors the growth environment and adjust nutrient solution, humidity and air temperature automatically depending on the conditions. The system used an Arduino Mega 2560 as the main control module with a Wi-Fi access point and an ESP8266 for Wi-Fi interface. The Arduino was communicated with a server that was developed and the server was deployed on a PC that connected to the Wi-Fi network. The results from the smart-farm showed that the lettuce from the farm had more leafs and wider stems compared to regular farm, hence they concluded that the overall quality of their produce is moderately better that that of regular farms. For future works the authors plan to use the collected data to create a prediction model for lettuce growth and yield.(Carri´on, Huerta, & Barzallo, 2018) Presented a low cost and power system that measures, monitors and automatically irrigates an urban garden using Internet of Things (IoT) technology. The system composes of three system being the mechanical, electronic and communication subsystems which also compose of carbon dioxide, temperature, humidity, detection of plants and luminosity sensors for remote monitoring and are all connected to a local area network. The system after taking all necessary reading creates a database set about environmental conditions, soil and crops for each user in case of multiple users for monitoring their gardens. In order for a farmer to access the information about their garden he logs in a web page application that will direct him to the full report on the state of the garden.(Rashmi R & Gaikwad, 2017) Proposed an automatic irrigation and crop security system in agriculture using Internet of Things that works by collecting, analyzing and monitoring real time sensor data such as humidity, temperature, PIR and soil moisture. The proposed system is supposed to take values every ten seconds from the environment and soil in order irrigation and crop security performance will be monitored automatically depending on the set threshold values. Threshold values have to be set for each soil variety as different variety of soils have varying water level demand. The system considers the level of water in the tank and soil moisture for automatic irrigation. For security purpose the system has a buzzer and scare crow that work hand in hand with a PIR sensor for detecting an object. The said system can be used by small scale farmers. The authors advance that the system has achieved ninety percent accuracy while they tested the prototype as well bringing notable gains such as saving water, money, crop security and soil and crop surveillance. The authors however are limited by the lack of use of the camera module to capture images detected by the PIR sensor and the use of sensors to detect the quality of soil to automatically dispense fertilizers.(Mhalakshmi, Priyanka, Rajaram, & Rajapriya, 2018) Designed and developed a low cost automatic irrigation system that is powered by solar energy using IoT.
