IoT-based smart energy meter

During this era of Industrial Revolution 4.0, the statistic of household appliances has drastically showing huge different of number in the recent years. This has made the consumption and demand for electricity increased time by time. Because of the diminishing the energy resources, a solution is needed to assist in tracking, measuring, and controlling electricity consumption. Due to the fact that conventional energy metres do not provide information on power usage at the system level, users are unable to track or log the amount of electricity used by individual appliances. To close the data gap on system energy usage, we propose investigating, implementing, and designing an Internet of Things enabled, minimalistic, cost-effective, and reliable smart energy metre that will assist consumers in obtaining information on their electrical appliance's energy consumption. This would not only assist customers in ensuring that their devices operate at the recommended energy consumption level. This will also make it simpler for them to access historical energy expenditure trends, which would lead to increased knowledge and conscious energy conservation. This system enables the users obtain their monthly consumption that has been calculated using TNB’s tariffs and also the electricity utilities organization able to obtain the meter’s reading monthly without their workers visiting each user’s house. This can be accomplished through the use of a IoT-Based smart energy meter module unit that continuously monitors and records energy meter readings in its permanent memory. This system continuously records the readings and, upon request, the consumer can view the live meter readings on a webpage smart phone or tablet. In the designed system, SDM230 digital energy meter is used as the input to measure and collecting the single phase electrical loads parameters and to be sent to the ESP32 microcontroller by using MODBUS RTU to TTL conversion. After the data sent, the microcontroller will calculate the monthly bill by using the energy data received. These data are sent again to the Blynk server by using Wi-Fi connection, and displayed on the user’s smartphone or the utilities provider

Mobile Ad-Hoc Networks

Being infrastructure-less and without central administration control, wireless ad-hoc networking is playing a more and more important role in extending the coverage of traditional wireless infrastructure (cellular networks, wireless LAN, etc). This book includes state-of the-art techniques and solutions for wireless ad-hoc networks. It focuses on the following topics in ad-hoc networks: vehicular ad-hoc networks, security and caching, TCP in ad-hoc networks and emerging applications. It is targeted to provide network engineers and researchers with design guidelines for large scale wireless ad hoc networks

An Evaluation of Tertiary Educators’ Perception of Online Teaching Related Ergonomic Factors

The Aim of this research was to identify and assess ergonomic factors that affected educators in minerals, mining engineering and other educators’ experience with online teaching. Noise, insufficient time to complete all teaching related work, and lack of interaction with students were the main barriers identified. There was minimal difference in factors between minerals, mining engineering, and other educators’ experiences. Having good physical, organisational, cognitive, social, and environmental ergonomic factors facilitated online educators’ work
