LoRaWAN for Smart Buildings Equipped with UVC Air Sterilizers

Today, people are getting more concerned about air quality and the increased risk of airborne infection. Among several, air sterilization is a solution that suits public buildings such as hospitals, airports, and laboratories. This work seeks to demonstrate how advanced IoT technologies like LoRaWAN can revolutionize the implementation practices for UVC air sterilization systems in controlling indoor air quality. The presented approach aims to leverage the capabilities of LoRaWAN, a low power, long range and wide area network, to monitor and manage the performance of UVC equipment remotely. The paper has studied through a detailed exploration of system architecture, implementation strategies, performance evaluation and compliance with safety standards. The experiment was carried out to address the challenges such as the impact of architectural barriers on signal propagation and potential interference from environments and other electronic devices. The control and notification module has been developed for analyzing these factors based on the measurement data of RSSI, SNR, and Noise. The experimental results reported the satisfactory performance of the operational efficiency of UVC air sterilizers to improved health outcomes, in addition to paving the way for smarter and more responsive sterilization solutions.
