Abstract
This paper introduces a modular and cost-effective IoT-based weather station using Arduino and STM32 microcontrollers. It captures temperature, humidity, pressure, rainfall, and light intensity using DHT11, MPX4115, LDR, and rain sensors. Data is transmitted via ESP8266 to Blynk Cloud and visualized on a mobile dashboard. The system includes circuit simulation, firmware logic, and PCB design, and is benchmarked against seven recent implementations.
