In this work we propose a non-wearable sensor based approach for longitudinal monitoring of the primary health conditions without using the wearables. The approach adapted is using the varied sensors and the algorithms to arrive at the non-obstructive continuous holistic monitoring of the primary health conditions (Obesity, Stress and Posture). The approach uses the slouch angle, curvature information, and deformity map to determine the type of the posture of the person, pressure sensors for obesity and stress is computed by analyzing the heart rate variability. The application of this approach is envisioned for the office based setting, pregnant women, bed ridden patients and for postoperative care.
