“…The ThingSpeak channel used 179863, allows up to eight fields such as relative humidity, temperature, soil moisture, flow of water, and location of the experiment. The MATLAB App was also incorporated for numerical computation to allow users to analyze and display the data with greater ease [21].…”

Environment Control with Low-Cost Microcontrollers and Microprocessors: Application for Green Walls

Green wall irrigation procedures are a particularly important and hard task, given that the quality of the green wall depends on them. There is currently a wide variety of irrigation programmers available, with a range of functions and prices, thereby replacing manual activities and making it easier to maintain green walls. This paper proposes the use of low-cost automated irrigation programmers via a freeware called Arduino. The system is based on air and substrate measurements to ensure optimal plant growth and high water-use efficiency. At certain thresholds, the irrigation system is activated. This not only makes irrigation more convenient but also helps to reduce energy consumption, increases irrigation efficiency and saves time. The data is then sent via Transmission Control Protocol using Internet of Things technology, in this case ThingSpeak. The platform compiles the data and presents them in simple graphical format, thus enabling real-time monitoring from wherever there is Internet access. Together with Arduino, the project incorporates the Raspberry pi system that operates like a database via Hypertext Transfer Protocol Wi-Fi received by a Structured Query Language (MySQL) server using Hypertext Preprocessor. These data are used for the subsequent analysis of green wall performance.

“…The significance of student satisfaction is widely reported on in literature [29][30][31]. Satisfied students will among other things make positive recommendations to other students [32], continue their study until graduation [33], provide word of mouth marketing for higher educational institutions [34] and have a general positive influence on the educational process.…”

A key graduate attribute for engineering students is the design and development of solutions for real-life problems. Enabling students to grasp engineering design principles often proves challenging, especially within the African context. The purpose of this paper is to highlight how the introduction of the Arduino microprocessor into a design-based module for undergraduate students has yielded outstanding results in this regard. Up until the end of 2014, students could choose their own microprocessor platform for designing electronic circuits required for specific applications. However, this led to several challenges, including the unavailability of components and the high costs of the microprocessors. Introducing the Arduino microprocessor as the preferred option in 2015 overcame many of these challenges, while at the same time leading to an improvement in the academic achievement of the registered students. A case study was used in this research along with descriptive statistics of the collected data. This data highlights that more than 90% of the students successfully completed this design-based module, while 70% felt that it really helped them to better understand the theoretical knowledge. This microprocessor has been recommended for future use in additional modules as it yielded positive results in 2015.

“…The course structure (highlighting six different submission requirements) used by the Electrical, Electronic and Computer Engineering Department at the Central University of Technology (CUT) for this module is shown in Table 1, which must be completed over a 10-month period (registration is completed in February with the final summative report submitted in October). The Department's objective is to provide quality education to students with regard to both electronic and power engineering, where the principles and application of electricity, electronics, electrostatics and electromagnetism are discussed (Hertzog & Swart, 2015). No formal electrical or electronic based circuits are required from these students who often work on high voltage systems (up to 132 kV).…”

Final Pass Rate Fluctuations of Power Engineering Students May Be Related to Load Shedding, and not Load Shifting

Power engineering students need to register for and successfully complete a capstone module within the Baccalaureus Technologiae qualification in Electrical Engineering in South Africa. These students need to submit six different assignments over a period of 10 months, comprising a proposal, a progress report, a poster, a power point presentation, a conference paper and a final report. However, it has been observed that the final grades of working students have fluctuated dramatically over the past three years, leading to the following research question “What may be contributing to these fluctuations?” The purpose of this paper is to discuss the fluctuations and provide possible reasons for them based on literature applicable to this field. An exploratory case study is used to provide quantitative data of the student final grades from 2014 – 2016. Results show that the pass rate varied from 71% to 77% to 56%. Furthermore, some 18 students submitted their proposal in 2016, but never submitted the other five assignments. This concern may be related to load shedding by both students and academics, rather than load shifting. A key recommendation of this research is to share its findings with top management of student employers and the university, thereby hoping to create awareness of the importance of lightening the workloads of employed students andacademics during important submission periods of capstone modules.
