Abstract: The advancement of Internet of Things (IoT) technology has enabled the development of smart environmental monitoring systems with real-time data accessibility. This paper presents the design and implementation of an IoT Based Smart Weather Monitoring System using ESP32 microcontroller and cloud analytics. The proposed system monitors environmental parameters such as temperature, humidity, and rainfall using DHT11 and raindrop sensors. The collected data is displayed locally on an LCD display and simultaneously transmitted to the ThingSpeak cloud platform through Wi-Fi connectivity for remote monitoring and analysis. The system offers low cost, low power consumption, and efficient real-time weather monitoring. The developed prototype can be effectively used in smart agriculture, environmental monitoring, disaster management, and smart city applications. The integration of cloud technology with embedded systems improves accessibility, reliability, and data visualization compared to traditional weather monitoring systems.
