| dc.description.abstract | Increased concentrations of ammonia (NH₃) in livestock buildings pose significant risks to animal welfare, environmental sustainability, and worker safety. The current study presents the design and validation of an Internet of Things (IoT) based sensor node to monitor ammonia concentration (NH₃) in real time in agricultural environments. A microcontroller for local data processing and a wireless communication module that transmits measurements to a cloud platform or mobile application. The prototype has been tested both in controlled laboratory conditions and on real livestock farms, demonstrating high accuracy (±5 ppm), low power consumption (battery power and additional solar panel), and resistance in dusty and humid environments. The collected data is analyzed using machine learning algorithms to predict dangerous levels of NH₃ and automate ventilation controls. The results show that the proposed solution offers a cost-effective and scalable approach to reduce NH₃ emissions, improve animal welfare, and ensure regulatory compliance. Future work includes the integration of additional parameters (e.g., temperature, humidity) and implementation in smart farming systems. | |
