Many diseases, such as cardiovascular and dengue
fever, require constant monitoring of certain health parameters
of patients which sometimes, is disturbing to patients who
requires plenty of rest. In this paper, we present a non-invasive
technique based on wireless sensor networks to monitor the
temperature, blood pressure and the pulse rate automatically
without having to disturb a resting patient suffering from
Dengue fever. The wireless sensor node captures these vital
health parameters and then sends them to a smart phone via
Bluetooth. The smart phone handles all the processing tasks and
produces systolic and diastolic heart rates and gives alerts
whenever an abnormal condition occurs. The prototype device
managed to perform at 99.76 %, 88.40% and 92.70% accuracy
levels on monitoring the temperature, blood pressure and pulse
rate, respectively. The system, designed using low-cost
peripherals with minimal electronic devices, can be used to
monitor dengue patients even from a remote location via
wireless technology.
