Abstract

The increasing demand for sustainable electricity requires hybrid renewable energy systems capable of improving power supply reliability and operational supervision under variable energy-source conditions. Purpose: This study aims to design and implement a laboratory-scale hybrid renewable energy control system integrating an Archimedes screw turbine and a photovoltaic system with PLC-based control and SCADA monitoring. Methodology: An experimental design and implementation approach was employed by integrating renewable energy generation, battery storage, electrical measurement devices, an industrial PLC, HMI, and cloud-based SCADA platform. Electrical voltage, current, power, energy, battery condition, and load status were acquired during laboratory testing and evaluated based on the functionality of monitoring, data logging, trend visualization, alarm notification, battery protection, and load control. Findings: The developed system successfully integrated renewable energy generation and industrial automation into a unified supervisory platform. The PLC continuously acquired electrical parameters, executed battery protection and load-switching logic, and communicated with the HMI and SCADA system. Real-time monitoring, historical data recording, graphical trend visualization, alarm notification, and remote load control operated successfully during experimental testing. Implications: The proposed architecture provides a practical platform for renewable energy monitoring, industrial automation education, and further development of automatic energy management and predictive supervision systems. Originality: Unlike previous studies that primarily focus on photovoltaic performance, Archimedes screw turbine optimization, or SCADA architecture separately, this study integrates photovoltaic generation, an Archimedes screw turbine, battery storage, industrial PLC control, HMI visualization, and cloud-based SCADA monitoring within a single laboratory-scale hybrid renewable energy platform.

Abstract

Coil-on-plug (COP) ignition faults can involve the coil, connector, harness, and electronic control unit (ECU), yet a single workshop case cannot establish the initiating component or transient chronology. This evidence-classified diagnostic case examined one Daihatsu Xenia 1.0 Non-VVT-i with an EJ-DE three-cylinder gasoline engine presenting vibration, misfire, reported loss of power, and reported increased fuel consumption. The available field record documented visual inspection, multimeter observations of supply and ignition trigger/feedback (IGT/IGF) lines, coil substitution, guarded substitution with a known-good ECU, on-board diagnostics II (OBD-II) scanning, internal ECU and connector inspection, corrective repair, and preliminary workshop verification. The multimeter did not detect comparable IGT/IGF indications on cylinders 2 and 3; replacing the suspected coils did not resolve the symptoms; and the donor ECU displayed diagnostic trouble codes (DTCs) P0300, P0352, P0353, and P0171. Degraded female connector contacts and visible damage along the original ECU ignition-driver path were subsequently observed. Repair of the documented defects was followed by restored continuity and stable operation during an unspecified workshop observation period. The evidence supports system-level diagnosis of an interconnected coil-connector-ECU fault, but not a proven cascade from coil switching to ECU damage. The principal contribution is a transparent reporting framework that separates direct observation, diagnostically supported interpretation, and unmeasured mechanism. The case also provides a safety-conscious diagnostic sequence for workshop and proposed vocational-learning use.

Abstract

This study designed and implemented a prototype paddy-husk separator that integrates a 200 Wp off-grid photovoltaic (PV) power system with vibrating-sieve and pneumatic separation. The mechanical assembly uses a hollow-steel frame, a perforated sieve, an eccentric drive, and a fan, while the electrical subsystem comprises a solar panel, a solar charge controller, a 12 V battery, and a 1000 W inverter. Prototype tests were reported at input loads of 10, 15, and 20 kg. The measured AC load remained at 126-132 W, which is below the inverter power rating. The pulley ratio of a 50 mm motor pulley and a 12-inch driven pulley yields a calculated sieve-shaft speed of 196.85 rpm, compared with a 214 rpm design target. Under the reported test conditions, the highest observed processing capacity was 723 kg/h at a 15 kg input load, whereas the highest reported separation efficiency (86.2%) and the lowest reported loss (1.50%) occurred at 20 kg. These results demonstrate the feasibility of integrating off-grid PV power with dual mechanical-pneumatic separation at prototype scale. However, the study does not document paddy variety, moisture content, replicate-level variability, or the full mass-balance record used to reconstruct separation efficiency and losses; therefore, field reliability, solar autonomy, and broader performance claims require further validation.

Abstract

This study aims to evaluate the responsiveness of the MAX6675 sensor regarding motor movement within an Arduino Uno-based Conveyor system. Testing was conducted to assess the sensor's ability to detect temperature changes and to observe the motor control system's response based on the measured temperature. The MAX6675 sensor served as the interface module for a K-type thermocouple, while the Arduino Uno acted as the central controller and a DC motor functioned as the Conveyor actuator. Temperature readings were displayed on an LCD, allowing for the observation of temperature fluctuations during the testing process. The methodology involved subjecting the K-type thermocouple to incremental temperature changes and monitoring the DC motor's response to the temperature values ​​read by the MAX6675. Data collected included temperature values, motor status, sensor response time, and the time required for the motor to start or stop once the temperature reached a predetermined threshold. Tests were performed across various temperature limits to determine the system's responsiveness to temperature changes. The results demonstrate that the MAX6675 sensor effectively reads temperature changes from the K-type thermocouple and transmits data to the Arduino Uno to govern DC motor control. When the temperature remains below the set limit, the motor operates; conversely, when the temperature reaches the programmed limit, the Arduino signals the motor driver to halt the motor. Thus, this evaluation of MAX6675 sensor responsiveness establishes the relationship between detected temperature changes and motor movement within the Conveyor system.
