The invention is related to a device to sense the pulse on a wrist of a subject and to arrive at the health status of the said subject by capturing the pulse in real time; analyzing the pulse based on time-frequency properties of the pulse signal and Vata, Pitta and Kaphahumors of the subject. The device reliably detects and captures noise free pulse characteristics of a subject at the appropriate locations of the subject's wrist with minimal positional error in a user friendly way with minimal reliance on the expertise of the person measuring the pulses. The device facilitates the analysis of the pulses and provides a comprehensive diagnostic system based on the pulse characteristics, visual features, responses of a subject to structured queries to arrive at the tridosha levels in a subject.
