The method is time consuming, prone to errors and unfairness in the process. An NFC-based attendance and course verification system is presented in this study. The system reads student’s data from the school ID card when brought in close proximity with an NFC module and sends the data to a web application where the attendance is taken and course(s) is verified as applicable. The technique is simple, cost effective and saves time. The developed system takes less than 3seconds to take a student’s attendance while compared with the manual paper-based method which took an average of 17secondsItem Development of 3-Axes Accelerometer Wireless Sensor Nodes for Pipeline Monitoring(2019) Ayinla, S.L.; Ajiboye, A.T.; Yusuf, A.O.; Dilibe, C.G.; Ajayi, A.R.Item Development of a Fuzzy Logic based Offline Handwritten Character Recognition System(2023) Ajayi, A.R.; Ajiboye, A.T.; Yusuf, O.A.; Adebayo, O.F.; Olawole, E.T.Item Effects of PID Controller on Performance of Dish Antenna Position Control for Distributed Mobile Telemedicine Nodes(Faculty of Engineering, University of Maiduguri, Nigeria, 2019) Ajiboye, A.T.; Ayinla, S.L.; Ajayi, A.R.Item Effects of PID Controller on Performance of Dish Antenna Position Control for Distributed Mobile Telemedicine Nodes(Faculty of Engineering, University of Maiduguri, Maiduguri, Nigeria., 2024-06) Ajiboye, A.T.; Ajayi, A.R.; Ayinla, S.L.Item Graphical method for determination of MQ series gas sensor circuit parameters for a standalone gas alarm system(Southern brazilian journal of chemistry, 2021) Ajiboye, A.T.; Opadiji, J.F.; Ajayi, A.R.Item Graphical method for determination of MQ series gas sensor circuit parameters for a standalone gas alarm system.(2021) Ajiboye, A.T.; Opadiji, J.F.; Ajayi, A.R.Item Graphical method for determination of MQ-series gas sensor circuit Parameters for a standalone gas alarm system(2022) Ajiboye, A.T; Opadiji, J.F.; Ajayi, A.R.Item Liquefied Petroleum Gas Concentration Monitoring System with Alarm and Cloud-Based Logging(Faculty of Engineering, University of Benin, Benin City, Edo State, Nigeria, 2021) Ajiboye, A.T.; Opadiji, J.F.; Popoola, J.O.; Ajayi, A.R.Item Mesh Plot- Based Analytical Selection Of Optimal Mq-Series Gas Sensor Parameters(Faculty of Computing and Informatics, LAUTECH, Ogbomoso, Oyo State, Nigeria., 2024) Ajayi, A.R.; Adebayo, O.F.; Ajayi, M.O.Metal Oxide Semiconductor or MOS-Type gas sensors are a type of sensors that can detect presence of some volatile, oxidizable or reducible substances in an environment. The sensitivity of these sensors depend on the selection of the appropriate parameters in terms of the sensor resistance in clean air (𝑅𝑜) and the load resistance value (𝑅𝐿). A mesh plot analytical method for determing these parameters is presented in this paper. The model equation for MQ-135 sensor as a case study was derived and this was used to generate the mesh surface plot of the various relationships existing between the different parameters leading to the selection of the optimal value that can give a useful sensor output voltage. The mesh surface plot of 𝑅𝑜 (Ω), 𝑅𝑠 (Ω) and concentration (ppm) and as well as the plot of 𝑅𝐿(Ω), 𝑉𝑅𝐿(V) and 𝑅𝑠(Ω) were critically examined. The result of the simulation shows that, for optimal sensor output in MQ-135 sensor, the 𝑅𝑜 value must be selected to be at a value of 30kΩ and the load resistor 𝑅𝐿 at a value of 47kΩ for effective sensor output.Item Undergraduate computer engineering laboratory manual (Vol. 2): measurement & instrumentation; digital electronic circuits; data communication & networks.(Published by Department of Computer Engineering, University of Ilorin, Ilorin, Nigeria, 2017) Opadiji, J.F.; Ajiboye, A.T; Olatunji, S.A.; Ayinla, S.L.; Ajayi, A.R.; Yusuf, O.A.; Labiran, O.O.; Mahmud, H.O.; Adebayo, O.F.Item Undergraduate computer engineering laboratory manual (Vol. 2): signal measurement & instrumentation; digital electronic circuits; data communication & networks(Department of Computer Engineering, University of Ilorin, Ilorin, Nigeria, 2017) Opadiji, J.F.; Ajiboye, A.T.; Olatunji, S.A; Ayinla, S.L.; Ajayi, A.R.; Yusuf, O.A.; Labiran, O.O.; Mahmud, H.O.; Adebayo, O.F.Item Undergraduate computer engineering laboratory manual (Vol. 3): microprocessor system interfacing; prototyping and packaging; artificial intelligence applications(Department of Computer Engineering, University of Ilorin, Ilorin, Nigeria, 2018) Opadiji, J.F.; Ajiboye, A.T.; Olatunji, S.A.; Ayinla, S.L.; Ajayi, A.R.; Yusuf, O.A.; Mahmud, H.O.; Adebayo, O.F.Item Undergraduate computer engineering laboratory manual (Vol. 3): microprocessor system interfacing; prototyping and packaging; artificial intelligence applications.(Published by Department of Computer Engineering, University of Ilorin, Ilorin, Nigeria., 2018) Opadiji, J.F.; Ajiboye, A.T.; Olatunji, S.A.; Ayinla, S.L.; Ajayi, A.R.; Yusuf, O.A.; Mahmud, H.O.; Adebayo, O.F.
