Abstract
The “Embedded System for Real-time Weather Data Collection” project is designed to provide continuous and accurate monitoring of weather conditions by utilizing embedded systems integrated with a range of environmental sensors. This system captures real-time data on various weather parameters such as temperature, humidity, atmospheric pressure, wind speed, wind direction, and rainfall. The data is transmitted to a central server for processing, analysis, and visualization, enabling users to access real-time weather information through web or mobile applications. This system is particularly useful for meteorological research, agriculture, disaster management, and smart city applications, where timely and precise weather data is critical for decision-making and planning.
Existing System
Traditional weather monitoring systems often rely on fixed stations that are limited in number and geographical coverage. These systems may not provide real-time data, making it difficult to respond promptly to sudden changes in weather conditions. Additionally, traditional weather stations are typically expensive, large, and require significant infrastructure, making them less suitable for deployment in remote or resource-constrained environments. The data collected is often processed and made available after significant delays, which can limit its usefulness for real-time applications like disaster response or precision agriculture.
Proposed System
The proposed “Embedded System for Real-time Weather Data Collection” addresses the limitations of traditional systems by deploying a network of compact, cost-effective, and easily deployable embedded systems equipped with environmental sensors. These systems continuously monitor weather parameters and transmit the data in real-time to a central server. The data is then processed and made available to users through a user-friendly interface, enabling them to monitor weather conditions, receive alerts, and make informed decisions based on accurate, up-to-date information. The system’s modular design allows for easy expansion and customization based on specific requirements, making it suitable for a wide range of applications.
