Item Automatic Recognition and Classification of Medicinal Plants: A Review(Academic Press, 2019) Ogidan, Olugbenga Kayode; Onile, Abiodun EmmanuelSome existing methods for recognizing and classifying medicinal plants are manual, cumbersome, and time-consuming. In this chapter, a comprehensive review of recognition and classification of medicinal plants using Information Communication Technologies (ICT) – Automated Techniques are presented. The study focuses on the recognition and classification of medicinal plant’s leaves using image processing-based and spectroscopic identification techniques. The work reveals that the image processing-based recognition method is more predominant in literature than the spectroscopic method of recognizing medicinal plants. Analysis of previous studies reveals that image processing-based and spectroscopic recognition methods are less cumbersome, faster, and non-destructive when compared to the chemical method. The details of various implementation platforms that are required for effective recognition and classification of medicinal plants are also presented in this chapter. It is believed that with the techniques outlined in this study, more people, including non-experts using electronic devices, would be able to easily recognize and classify medicinal plants. This would offer better insights into their usefulness and conservation for the benefit of the future generation.Item Optimal solar power for control of smart irrigation system(IOP Conf. Series: Materials Science and Engineering, 2021) Ogidan, Olugbenga Kayode; Amusan, Akinwumi Abimbola; Temikotan, Kehinde Olusesan; Nkanga, Iniubong EssienIrrigation is very vital to food security but deployment of effective irrigation requires solar energy especially in the rural areas with no grid power. In this work, the optimal power required in the solar photovoltaic (PV) and the battery of a solar powered system (at any instance) for effective operation of a smart irrigation facility in Elizade University Ilara Mokin, Nigeria is determined. The system uses current and voltage sensors placed at the solar photovoltaic (PV) and the battery sections to perform real-time measurements on irrigation solenoid valves. Acquired current and voltage sensor values are passed to a microcontroller, readable in the computer serial monitor and later used to compute the required power in both PV and battery sections. The developed solar power system was implemented on a pilot farm with irrigation facilities consisting of sensors (moisture content, water level) and actuators (three solenoid valves). Tests were performed under the load-on condition. Results obtained reveal a maximum power threshold of 72.68 W for the solar PV and 14 W for the battery when three solenoid valves were loaded or operated at the same time and a minimum value of 31.55 W for the solar PV and 1.9 W for the battery when one valve is operated. The power thresholds obtained would be useful for configuring the smart irrigation system controller to ensure adequate delivery of water to crops as well as prolong the lifespan of the developed solar powered system.Item Smart irrigation system with an Android-based remote logging and control(IEEE, 2020-07) Ogidan, Olugbenga Kayode; Afia, Kennedy RichmondIn order to eliminate the drudgery associated with irrigation practice, a smart irrigation system with an Androidbased mobile application and control system is developed and tested under the local and cloud server architectures. The system uses four sensors (moisture content, temperature, humidity and ultrasonic) to acquire real-time data from the irrigation site which are fed to the central controller. Wi-Fi device is used to provide Internet connectivity to a local and cloud server. A mobile application is developed to display the four sensor measurements on a user-friendly graphically interface in real-time as received from the server. The system automatically starts/stop irrigation pumps based on measurements received from the soil moisture content sensor after attaining certain threshold values. Its remote logging capability makes it possible for users to view on their mobile phone the status of their farmland such as atmospheric temperature, humidity, level of water in the reservoir and soil moisture content from any location, provided Internet access is available. It also gives the user the flexibility of starting a pump on the farmland remotely using his mobile device. Experimental results reveal that the local server is more stable than the cloud server architecture.Item Smart Irrigation System: A Water Management Procedure(Agricultural Sciences, 2019-01) Ogidan, Olugbenga Kayode; Onile, Abiodun Emmanuel; Adegboro, Oluwabukola GraceThis paper presents a smart irrigation system suitable for use in places where water scarcity is a challenge. In many parts of Africa, even when irrigation is practiced, it is manually operated. Smart irrigation system is thereby believed to be a major solution. The paper therefore presents a smart irrigation system that optimizes the available water in the water reservoir thus providing an ef-ficient and effective water usage solution for the irrigation system. The irriga-tion system is able to automatically start/stop water pumps on the irrigation site based on the soil moisture content acquired from the moisture content sensor as well as the ultrasonic sensor measuring the water level in the reser-voir. The measured sensor values are sent to the Arduino microcontroller for configuring the control algorithm. The system prioritizes irrigation operation by determining the number of pumps to be operated at any instance as well as their locations. In this way, different crops can be watered depending on their varying water requirements. In order to implement the design, a laboratory scale architectural model depicting a farm setting with reservoir, direct cur-rent (DC) pumps and the control unit was constructed. Experimental results revealed good performance which makes the developed system a suitable tool for studies on irrigation.
