LoRaWAN-Based IoT Monitoring Systems for Sustainable Smart City

The urgent demand for sustainable smart city solutions, fueled by rapid urbanization and environmental concerns, has prompted the adoption of advanced technologies to enhance living standards and resource efficiency across various sectors. LoRaWAN technology emerges as an effective and affordable means to connect sensors in urban areas, addressing challenges such as scalability, energy consumption, and high deployment costs, faced by many smart city initiatives. This research tackles these issues by implementing four key low-cost monitoring systems: air quality, environmental, liquid flow and level, and smart streetlights. Contributing to a more sustainable urban environment, we design and deploy LoRaWAN-based systems equipped with sensors, and strategically placed gateways for optimal coverage. The collected data is transmitted to a central network server which can be accessed remotely for real-time monitoring and analysis. The result confirms that LoRaWAN-based monitoring systems efficiently gather and transmit data with low energy use, Implementation of these systems in smart cities enhances urban planning, resource management, and sustainability, facilitating proactive pollution control and cost reduction.
