Real-Time Weather Forecasting Using BME280 and STM32 Microcontroller

Weather has a significant impact on human activities and important decisions, such as planning a trip, landing an airplane, and planting crops. These decisions are greatly aided by precise weather prediction and monitoring. This study presents the design and construction of a low-cost, mobile weather monitoring and forecasting system capable of gathering, reporting, and storing various meteorological parameters. The system was initially designed using Proteus software and implemented with a BME280 sensor, which measures environmental variables including altitude, wind speed, precipitation, temperature, pressure, humidity, and heat index. This sensor was integrated with an STM32-bit microcontroller that processes the weather parameters. A storage module was embedded to store data, while real-time weather conditions are displayed on an LCD screen. The system processes the weather information and displays the current weather conditions on the LCD. The corresponding data, stored in the embedded storage system, is collected and presented in this study. The results demonstrate the system's ability to accurately present real-time weather conditions based on sensor data. The constructed system is portable, cost-effective, and accurate in providing weather information across different locations.
