AQORTA (Air Quality and Noise Real Time Data Acquisition) An Integrated Air Quality and Noise Telemetry System with Solar Power System

ID Patent: P00202112421

The AQORTA system invention pertains to the implementation of a telemetry system for air quality and noise monitoring, capable of recording measurement data into a MySQL database and displaying the measurement results through a Graphical User Interface (GUI) in real-time. The system consists of two components: hardware and software. The hardware component is installed at the measurement location and functions to record air quality data (CO, O3, temperature, humidity) and noise levels, transmitting the data to a MySQL database hosted on a web server. The software component is accessible via a website-based GUI and an Android smartphone application, enabling the visualization of measurement data in the form of gauge indicators, graphs, tables, and geolocation data using the Google Maps Application Programming Interface (API). The AQORTA system’s primary power supply relies on solar panels and a 12-volt DC battery regulated by a solar charge controller. The hardware’s energy consumption is 78.49 Wh per day.

Inovasi Sistem Pengukuran Kualitas Udara Terintegrasi Solar Power System Berbasis Internet of Things (IoT)

Penerbit Litnus (PT Literasi Nusantara Abadi Grup)

Permasalahan kualitas udara kerap kali menjadi masalah yang sering terjadi baik di kota-kota besar dan juga pinggiran. Polutan yang berasal dari kendaraan bermotor dan industri yang kemudian dibuang ke lingkungan, pembukaan lahan dengan cara membakar hutan atau belukar akhirnya menjadi perangkap radiasi matahari sehingga mengakibatkan suhu meningkat dan efek iklim mikro menguat. Permasalahan terkait lingkungan dan manusia ini kemudian memerlukan tindakan mitigasi untuk memperkuat sistem informasi kebencanaan khususnya mengenai kualitas udara. Buku ini memaparkan inovasi dari hasil penelitian untuk mengatasi permasalahan tersebut yaitu berupa alat untuk mengukur kualitas udara secara portable berbasis Internet of Things (IoT). Inovasi yang dilakukan adalah alat dapat menampilkan data real time melalui koneksi internet dengan memanfaatkan website dan smartphone android sebagai Graphical User Interface (GUI). Selain itu untuk wilayah pinggiran/rural dipaparkan pula inovasi berupa penggunaan teknologi Long Range (LoRa).

Anti Theft Power Smart Metering System

International Conference on Technology and Policy in Energy and Electric Power (ICTPEP) 2024 at Bali, Indonesia

PT PLN (Persero) which has more 89,1 million customer plays important role to distribute electricity to people. Even though PT PLN still has many problems on of which is losses energy in distribution system. Distribution system came from substation to 20KV line to distribution substation and then to kWh meter. Distribution losses can happen in two that is technical losses and non-technical losses. One of many reasons is happened in kWh meter. In PT PLN has two system kWh meter that is postpaid and prepaid. Postpaid still use conventional system that has to be reading physically by custodian and prepaid system use buying token before we use kWh meter. Postpaid system can’t detect theft electricity from customer just using conventional system. With microcontroller, IC power energy watt meter and GSM GPRS module we can build system that detect theft electricity and avoid non-technical distribution losses. The IC power energy meter STPM10 can calculate highly accurately voltage, current, active power, reactive power and frequency of line power. The module can send data to local server in distribution substation and analyze usage of distribution substation deviation with amount of usage kWh in the same distribution system.

Exploring the Relationship between Solar Panel Adoption and Socio-Economic Factors: A Case Study of Urban Households in Developing Countries

Journal of Electrical Systems 20-5s (2024): 2737-2754

This article will discuss the results of research on how the use of solar panels as an alternative energy source is related to social and economic factors, especially in urban areas in developing countries. This study will analyze factors such as education level, income, and people's perceptions of alternative energy to identify correlations between solar panel use and socio-economic variables. It is hoped that this article can provide new insights for public policy in promoting the use of renewable energy and creating a more inclusive society. This research can be categorized as quantitative. The research method used is the associative research method. The data analysis method used is correlation analysis. The sampling technique used is purposive sampling. The results of the study show that there are different characteristics of the relationship between the use of solar panels and socio-economic variables. Research on the relationship between global solar panel use and factors such as the number of prosumers, total kwh exports, GRDP, total investment, total load, home charging ev, distance to the capital city, air quality, and per capita expenditure has very important uses for stakeholders, especially in terms of sustainable energy development and reducing negative impacts on the environment. Policymakers can use the results of this research to formulate more appropriate policies to promote the use of solar energy and drive the shift to renewable energy sources.

A Telemetry System for Real-Time Air Quality and Noise Monitoring in Urban Areas Based on IoT Technology

Tuijin Jishu/Journal of Propulsion Technology

Large urban agglomerations inevitably lead to air pollution. The sustainable control and monitoring of air pollution have been lacking in many cities including air quality and noise information was difficult to be accessed by the citizens periodically. This paper aims to design an air quality and noise telemetry systembased on internet communicationwhich can record the measurement data into MySQL database and showing the data through a GUI in real time. The system was developed by using solar panel as a main power supply with Arduino Uno R3 as a microcontroller board, ENC28J60 as an ethernet module and various environmental sensors like MQ7 (CO gas), MQ131 (Ozone gas), KY-038 (Noise), Dust Sensor GP2Y1010AU0F (PM10) and DHT11 (Temperature and Humidity). The system has been tested through an in-field experimentation performed in different areas of Pontianak City. Electrical energy consumption was 78,49Wh in a day. According to the test results, the system could work properly for both hardware and software.
