Conventional patient monitoring systems exhibit critical limitations including fragmented physiological data acquisition, delayed critical event notification, and prohibitive deployment costs. These constraints impede timely clinical intervention and exacerbate healthcare accessibility challenges, particularly in resource-constrained environments. To address these deficiencies, this paper presents a novel dual-controller architectural framework integrating multi-modal biosensing capabilities with real-time analytical functions. The implemented system features comprehensive physiological surveillance of cardiac, oximetric, thermal, and mobility parameters through tightly synchronized edge processing. Core innovations include clinician-centric visualization via an embedded web dashboard, automated electronic alerting for critical health anomalies, cloud-enabled longitudinal analytics, and redundant local diagnostics. Rigorous operational validation confirms exceptional system reliability, responsive clinical alerting, significant cost efficiency, and measurable reduction in caregiver workload. This research establishes a new paradigm for accessible high-fidelity patient monitoring through harmonized hardware-software co-design, enabling deployable continuous health surveillance across tertiary hospitals, community clinics, and remote care settings.
