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.

Pengukuran besaran frekuensi sangat penting peranannya dalam bidang sistem pengukuran sinyal terutama untuk akuisisi data sinyal pulsa pada pengukur aliran jenis turbin. Untuk memenuhi kebutuhan pengukuran yang akurat dan menjadi mandiri secara teknologi diperlukan produk frekuensi meter lokal yang terkalibrasi. Tujuan penelitian ini adalah membuat prototipe frekuensi meter sampai rentang ukur 2000 Hz yang terkalibrasi sehingga terjamin nilai kebenaran pengukurannya secara internasional. Digunakan mikrokontroler board Arduino Uno dengan kemampuan pencacah 16 bit untuk menghitung frekuensi. Hasil pengukuran ditampilkan secara real time komunikasi serial sertapada Liquid Crystal Display (LCD). Telah dilakukan kalibrasi prototipe frekuensi meter tersebut menggunakan standar DS340 yang telah tertelusur ke satuan SI melalui standar primer frekuensi cesium Puslit Metrologi LIPI. Dari hasil kalibrasi dan pengukuran pada rentang ukur (10 ~2000) Hz didapat bahwa prototipe frekuensi meter ini memilikikemungkinan error terbesar sebanyak 0,7 Hz. Telah berhasil dibangun ketertelusuran pengukuran prototipe frekuensi meter tersebut dengan resolusi 0,1 Hz dan akurasi 0,03% relatif skala penuh.

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.

Linear Correction

The gravimetric method, which is mainly used among particulate matter (PM) measurement methods, includes the disadvantages that it cannot measure PM in real time and it requires expensive equipment. To overcome these disadvantages, we have developed a light scattering type PM sensor that can be manufactured at low cost and can measure PM in real time. We have built a big data system that can systematically store and analyze the data collected through the developed sensor, as well as an environment where PM states can be monitored mobile in real time using such data. In addition, additional studies were conducted to analyze and correct the collected big data to overcome the problem of low accuracy, which is a disadvantage of the light scattering type PM sensor. We used a linear correction method and proceeded to adopt the most suitable value based on error and accuracy.

The Status

Internet of things is the present technology that permits us to control hardware via the internet. Using IOT system, we can link the physical devices and possess the ability to send or transfer data over a network with either human-to-human or human-to-system interaction. This paper explains how to control home appliances using Internet of Things. The microcontroller we are using for this project is Raspberry Pi. The Raspberry Pi is interfaced with Wi-Fi modem for transmitting and receiving commands over the internet. To switch loads, we are using relays. Once the user passes instructions over the internet to switch on the appliance, the raspberry pi processes these commands and operates accordingly. Liquid Crystal Display is used to display the status of the system. Hence, IOT based home automation setup allows us to control home appliances over the internet.

The Internet Civil Diplomacy is a major revolution and an emerging trend witnessed in the information age. It poses a significant impact on foreign affairs and official diplomacy due to its unique characteristics—freedom, equality, individuality, real-time, low-cost, and convenience. This chapter reviews the development of Internet-based civil diplomacy and the practice of China’s Internet-based civil diplomacy, which has been greatly developed in recent years in multiple forms—e.g. Web forums, website signatures, event-driven purpose-build foreign affairs sites. Two types of impact of the civil Internet diplomacy—expansion effect and resonance effect—have been examined in the Chinese context through cases, events, and examples. The chapter also identifies challenges and proposes solutions for future development of the civil Internet diplomacy in China.
