Abstract

Due to their high cost and tedious data collecting, traditional weather monitoring systems are frequently ineffective, prone to human error, and inaccessible. For sectors that rely on real-time environmental data to make educated decisions, like agriculture, urban planning, and disaster management, these restrictions provide difficulties. The necessity for a cost-effective, automated, and precise weather monitoring system that can deliver trustworthy data in real time is further highlighted by the speed at which climate change is occurring. This project suggests creating an ESP32-based Internet of Things weather monitoring system that is integrated with sensors like the FC-37 (rainfall intensity), BMP280 (atmospheric pressure), and DHT22 (temperature and humidity) in order to address these issues. The system records environmental data, sends it in real time to the Blynk IoT platform for remote access, and shows it locally on an LCD. By offering a scalable, affordable, and user-friendly substitute, this creative solution seeks to enable both individuals and businesses to efficiently monitor environmental conditions. The system's accuracy and dependability were validated by extensive testing, which makes it a powerful and long-lasting instrument for encouraging data-driven decision-making and climate resilience.
