Environmental awareness, current trends in the power market, the quest for energy efficiency, and the progressive transformation of electricity consumers to prosumers are the primary drives for the gradual shift from the old power grids into the smart grids. The deployment of renewable dispersed generation systems and energy storage units uncovered the need for smart metering to oversee and control those generation systems. This chapter presents the design and development of a robust, efficient, multi-functional, and low-cost smart meter. The proposed metering system has added features that enabled the utilities to recover the meter energy measurement data remotely. The system allows monitoring and transmission of energy consumed in real-time. It considers using a microcontroller board as the controlling unit to execute control and monitor activities. A liquid crystal display displays standard electrical measurements such as current, voltage, power, and energy consumption. The external communication device is required in the unit’s actualization, in conjunction with the control unit based on the existing mobile technology. It stands as the intermediary between the nearby available utility station and consumers or end-users. In conclusion, liquid crystal display displays real-time based data for the end-user to visualize. The usage data billing is done within thirty seconds, stored, and trans-received the process for data collection, keeping, and billing generation.

Background: Weather monitoring is an important aspect of crop cultivation for reducing economic loss while increasing productivity. Weather is the combination of current meteorological components, such as temperature, wind direction and speed, amount and kind of precipitation, sunshine hours and so on. The weather defines a time span ranging from a few hours to several days. The periodic or continuous surveillance or the analysis of the status of the atmosphere and the climate, including parameters such as temperature, moisture, wind velocity and barometric pressure, is known as weather monitoring. Because of the increased usage of the internet, weather monitoring has been upgraded to smart weather monitoring. The Internet of Things (IoT) is one of the new technology that can help with many precision farming operations. Smart weather monitoring is one of the precision agriculture technologies that use sensors to monitor correct weather. The main objective of the research is to design a smart weather monitoring and real-time alert system to overcome the issue of monitoring weather conditions in agricultural farms in order for farmers to make better decisions. Methods: Different sensors were used in this study to detect temperature and humidity, pressure, rain, light intensity, CO2 level, wind speed and direction in an agricultural farm and real time clock sensor was used to measured real time weather data. The major component of this system was an Arduino Uno microcontroller and the system ran according to a program written in the Arduino Uno software. Result: This is a low-cost smart weather monitoring system. This system’s output unit were a liquid crystal display and a GSM900A module. The weather data was displayed on a liquid crystal display and the GSM900A module was used to send the data to a mobile phone. This smart weather station was used to monitor real-time weather conditions while sending weather information to the farmer’s mobile phone, allowing him to make better decisions to increase yield.

Warga desa Regaji dalam mendapatkan air untuk kebutuhan sehari-hari masih mendapatkan adanya kendala seperti telat dalam mendaptkan kebutuhan air untuk sehari-hari, karena proses penyaluran air masih dilakukan secara manual. Oleh, karena itu dibutuhkan suatu alat yang dapat menghemat waktu dalam penyaluran air di desa Regaji. Alat tersebut berupa sistem yang dapat bekerja otomatis untuk penyaluran air, dengan menggunakan alat ini diharapkan penyaluran air dapat dilakukan tepat waktu dan pada saat yang tepat. Penelitian ini dilakukan dengan membuat suatu perangkat sistem untuk penyaluran air otomatis menggunakan mikrokontroler ATMega16 sebagai pengendali utama dan sensor ultrasonik. Sistem ini juga menggunakan Real Time Clock (RTC) sebagai pewaktu dan Liquid Crystal Display (LCD) sebagai penampil. Mesin pompa air otomatis yang telah dibuat dapat menyalurkan air secara otomatis, apabila waktu sudah berada pada jadwal yang telah ditetapkan, maka proses penyaluran air akan dilakukan secara otomatis dan LCD akan menunjukkan waktu saat ini.

A new LCD interface design is put forward in this paper. The design solves the problems of taking too much time to deal with data and different interfaces which exists in common LCD. With this method, it is not necessary to proceed time-consuming LCD control and dot matrix operation, which is in favor of real-time processing of mass data by controller.

In this paper, an architecture of a low-cost ARM-based Smart Metering network is presented. The system is designed to be suitable for Smart Grids applications aimed to a more efficient energy use according to the article 13 of Directive 2006/32/EC. The network is composed by several slave smart meters that continuously monitor loads and energy generators to make available information in real-time such as power and energy consumption/generation and several power quality parameters communicating them via CAN bus to specific master device called data aggregator. This device, integrating the information coming from field devices (energy demands of loads, the current energy production and co-generator status), with information obtained through the web access (a prevision on the expected availability of energy produced by renewable sources, current and future energy price, customer remote setting), can take decisions to implement a suitable energy management aimed to cost saving or whatever else strategy chosen by customer. Data aggregator also allows checking current consumption locally, thanks to a display, and remotely, using the web browser access. To prevent external attacks a low computational burden protection software based on Message Authentication Code (MAC) has been implemented. Finally, characterization test of realized apparatus have shown good performance both in terms of communication delays and measurement uncertainty.
