In response to the COVID-19 pandemic, WHO issued guidelines emphasizing social distancing as a primary preventive measure. Despite recommendations to maintain a 4 to 6 feet distance, adherence remains inconsistent. This research proposes an IoT-based solution using RSSI (Received Signal Strength Indication) for target detection within 1.5 meters. If a breach occurs, an indicator alerts the individual. Unlike many studies focusing on contact tracing, this approach emphasizes proactive social distancing. The portable device continuously monitors and alerts individuals when they fall below the 6-foot threshold. The proposed system significantly outperforms existing methods, achieving 57.7% higher accuracy, 26.7% greater sensitivity, and 48.1% improved specificity. It also reduces the false positive rate (FPR) by 89.7% and the false negative rate (FNR) by 89.6%, ensuring precise and reliable social distancing compliance.
