Wireless sensor networks (WSNs) harness LoRaWAN technology to provide cost-effective and long-range communication for environmental monitoring applications. These systems can track diverse parameters such as temperature, humidity, air quality, and soil moisture, enabling real-time data collection. LoRaWAN's inherent low-power consumption makes it s

Improving indoor environmental quality is paramount, and monitoring parameters like carbon dioxide (CO2) concentration plays a crucial role. This article explores the implementation of a cost-effective LoRaWAN-based system for real-time CO2 sensing within buildings. The robustness of LoRaWAN technology allows for long-range, low-power data transmis
