“…This error was greater than indicated in the datasheet because the sensor was affected by temperature (Dabou et al 2021). Another research also found that the MAE obtained from the validation of the ACS712 sensor was lower than 0.05 A (Jabbar et al 2022).…”

Ohmic heating is an emerging technology currently in high demand for application in various processes. In this research, a prototype of a multipurpose ohmic heating apparatus was successfully designed, fabricated, and tested. This apparatus was designed based on low-cost and versatile sensors and components available worldwide. Three independent chambers could be operated parallelly and individually with different treatments. Parameter data, i.e., voltage, electrical current, the temperature of heated material and environmental humidity-temperature, could be recorded by an embedded data logging system. The sensor had been tested and validated by comparing all the sensors used with commercial standard instruments. The result showed that all sensors had high measurement accuracy, indicated by very low mean absolute error (MAE) and mean absolute percentage error (MAPE), with R 2 > 0.999. The performance test revealed that product temperature could be accurately maintained according to the set point temperature with a deviation value lower than 0.1 °C. The data logging system was able to record and store the parameter data in SD card memory for up to several days without interruption. The prototype of the ohmic heating apparatus could be an effective alternative to process many purposes such as pasteurisation, cooking, warming, and fermentation based on the ohmic heating principle.

“…In 2021, the Web of Science TM library contained more than 13,000 indexed papers on the topic of IoT technology [ 56 ]. IoT technologies are deployed in many application areas, such as environmental monitoring [ 10 ], smart factories [ 57 , 58 ], smart cities [ 59 ] and smart grids [ 11 , 60 ]. Although IoT technology is widely deployed, only a few research articles cover the monitoring of geothermal energy installations.…”

Geothermal energy installations are becoming increasingly common in new city developments and renovations. With a broad range of technological applications and improvements in this field, the demand for suitable monitoring technologies and control processes for geothermal energy installations is also growing. This article identifies opportunities for the future development and deployment of IoT sensors applied to geothermal energy installations. The first part of the survey describes the technologies and applications of various sensor types. Sensors that monitor temperature, flow rate and other mechanical parameters are presented with a technological background and their potential applications. The second part of the article surveys Internet-of-Things (IoT), communication technology and cloud solutions applicable to geothermal energy monitoring, with a focus on IoT node designs, data transmission technologies and cloud services. Energy harvesting technologies and edge computing methods are also reviewed. The survey concludes with a discussion of research challenges and an outline of new areas of application for monitoring geothermal installations and innovating technologies to produce IoT sensor solutions.

“…These existing acquisition systems are based on software requiring operating licenses [6]. In addition, these systems are relatively complex and costly to use and in some cases, are also distinguished by the limited number of monitored parameters they offer in DC or AC [6] [7]. There are even commercial solutions with drawbacks in the communication protocols and knowledge of these systems, as they make it difficult for the user to add new functions [8], such as the monitoring systems included in the most popular commercial inverters.…”

“…In [9], a prototype of a PV module energy monitoring system developed in India is shown, which is remote and applies the Internet of Things (IoT) concept but only measures DC electrical parameters. In [7], a SEM-LoRaWAN smart energy meter was proposed to measure energy consumption and monitor various parameters such as voltage, current, power, energy, light intensity, temperature, and humidity and send them to the cloud using LoRaWAN technology. However, this technology has not yet been widely used to monitor PV systems, its performance is not yet known with certainty, and it can only acquire DC electrical parameters.…”

The rapid development of renewable energy sources, such as photovoltaic solar energy, makes it possible to sustainably cover part of the energy demand in different parts of the world. Thus, higher efficiency of photovoltaic systems is sought to provide higher yields, security, and stability in their operation and energy production. Therefore, it is crucial to monitor the variables of interest and verify the correct operation of photovoltaic systems. This article presents the development of a monitoring system that allows the acquisition and recording of the main electrical parameters, both in direct and alternating current, enabling the evaluation of the array and final yield of grid-connected photovoltaic systems. The developed monitoring system follows the concept of the Internet of Things for remote data analysis. In addition, it allows local data logging in a computer for data acquisition over a long period. The measurements of the developed monitoring system comply with the International Electrotechnical Commission standards specified in IEC 61724-1. This validation is performed after contrasting the measurements obtained by the developed system with those obtained by the high-precision WT5000 power analyzer, where the relative differences of each electrical parameter analysed are less than 2%. Finally, the system developed is characterised by its low cost, which is less than US$ 140.
