Abstract

Objectives: To develop an IoT (Internet of Things) based Solar Energized Weather Monitoring System (I-SOEWM) that incorporates efficient mechanism to receive real-time weather reports both locally and remotely. Methods: Improved localized weather monitoring system powered by a renewable solar energy has been developed to provide continuous real-time monitoring of parameters namely temperature, humidity, pressure, air quality, etc., The developed device is GPS-enabled to provide geo-localized data. The significance of the developed work is that the parameters measured are stored simultaneously on two cloud platforms namely Thingspeak and Adafruit, thereby ensuring reliability and security of the developed system. From the literatures, it is found that several works have been carried out that are closer to the developed research. However continuous monitoring is ensured in the developed work through Solar energy based renewable energy harvesting mechanism. Further, new parameters namely UV Index, Air Quality Index (AQI), and Dew Point are also monitored when compared to existing systems. Findings: Through the inclusion of additional parameters namely UV Index, AQI and Dew Point, the air quality, intensity of sun and the temperature at which air cannot hold water vapors are measured which lacks in the existing WMS. These parameters are vital for well-being of living organism. Novelty: The proposed system is solar-powered and incorporates real-time analysis of additional parameters. It has a long battery life (2.5 years for Li-ion) because the controller uses less power and an added solar panel is built into it, and it is capable of real-time data monitoring. (It also provides interfaces for mobile and web applications for user interaction.
